David, thank you for responding.

If anyone did not test the mainline kernel and posts to BZKO, it's most likely going to get ignored, or shutdown with impunity.
As well, nobody from the Ubuntu Kernel Team/Ubuntu Bug Control is steering Original Reporters to BZKO unless the problem is proven to exist in mainline, as per well documented UKT/UBC policies https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Reporting_Bugs_Upstream .

Now that you mention this, I did notice Greg Kroah-Hartman shutdown a handful of Linux USB bugs forwarded from Launchpad a few months ago, which I personally triaged and referred to BZKO as the bug existed in mainline. However, the ORs did not follow the BZKO format that was specifically noted in my comment, referring them to the current Reporting Bugs Upstream article iteration. Greg advised them to report their issue to the USB maintainer mailing list. Unfortunately, he did not mention the rationale for this action. I mean, come on, BZKO is a publicly viewable and postable _Bugzilla_. ;)
In spite of this, we can guess with a reasonable amount of certainty that the shutdowns happened because the ORs did not follow the BZKO format. In response to the GKH shutdowns, I stepped up the intensity of my wording in my comments to ORs, which got ~2/40 ORs to do it, increasing my prior batting average from 0%. :D
This is the driving factor for wanting to see the article improved by stepping up the intensity of the article wording and increasing the verbosity of explanation. I do not want to receive angst by proxy when I add myself to the CC.
Also, my intended improvement proved true, "Failure to follow these directions exactly as shown... may likely result in your bug being ... closed...". The ORs rolled the die and lost.
Ultimately, if BZKO developers decide mailinglist first only, then I agree falling in line with their request is the best way to go.

This is current UKT/UBC policy.

I do not agree that asking them to think about providing information is a bad idea. All the UKT/UBC documented responses do is politely ask, not demand, ORs for the developer "need to haves" to work on the bug downstream. Testing mainline is a "nice to have" providing the Ubuntu developer(s) more data points and opening up the OR to having more eyeballs look at their bug by BZKO devs. The current UKT/UBC debugging articles, my past article improvements, and my current improvment suggestions are focused on "copy from the article, paste into a terminal, hit enter, and post results into a comment" transactional debugging, that anyone from a child to a senior citizen could accomplish with little to no familiarity with a computer.
Some of the articles include more in-depth analysis on the transactional debugging, yet this exists for the technically inclined and curious. None are expecting an OR to whip up a patch because an analysis exists.

The BZKO format part:
[5.] Output of Oops.. message (if applicable) with symbolic information resolved (see Documentation/oops-tracing.txt)

is potentially daunting. More work would need to be done to transactionalize it. None the less, this transactionalization seems not to be a show stopper for the current suggested improvement being implimented, but something the Ubuntu community could work on adding in a near future improvement.

Currently, by the time an OR is asked to read the UKT upstream article, they have already apport-collect'ed in >= Precise, proved the bug is in mainline, and provided all relevant information from https://wiki.ubuntu.com/DebuggingProcedures . The BZKO format is to prepare any report from any distro to be posted on BZKO so a BZKO dev won't ignore/shutdown the report.

One could make the same arguement about any distro being pointed to BZKO if something was demonstrated in mainline. Never the less, nobody does this as per UKT/UBC policy. Launchpad is the only forum for Ubuntu users to get Ubuntu bugs fixed. BZKO is for mainline kernel bugs only. No confusion exists about this.

Positive outcomes are what happens when a Ubuntu OR follows the BZKO format:
https://bugzilla.kernel.org/show_bug.cgi?id=42993

Although, I did skip a couple parts. The ooptext part, which luckily was not relevant, and:
[7.1.] Software (add the output of the ver_linux script here)

which I skipped accidently out of ignorance. Again, luckily it was irrelevant.

I did not consider this. Your saying instead of using the mainline prebuilt binaries, build it from kernel.org source tarballs on the ORs computer? While I am not familiar with all the technical nuances of using the prebuilts versus building from source,
I do approve of and trust the current UKT/UBC policy in that if you test the prebuilts it's sufficient for BZKO, it's sufficient. So far, it has been when the upstream article is _actually_ followed.
The problem is ORs are not following the article. Not, the article is wrong in sending them to BZKO in the first place.
With this in mind, if the improved article cannnot better persuade ORs to follow it in very high percentages, the next step could be your first point how ORs should not be sent in the first place. A slightly more labor intensive, and considerably more productive solution would be for Ubuntu triagers/developers to further triage the upstream forwarded BZKO reports (not the downstream report) found not to follow the BZKO format. This would allay any BZKO developer frustration with ORs who do not follow the BZKO format.
While friviously shutting down bugs because the OR made a mistake for not providing the report in the BZKO format, especially when the maintainer/sub/community dev is subscribed to both the BZKO and the mailing list, is not very cool, let alone Ubuntu, disregarding the BZKO format when posting to BZKO, as well as not reasonably facilitating as many eyeballs on a Ubuntu community member's bug as possible, for whatever reason(s), is certainly not cool/Ubuntu.
Summing this part up, your point about how current policy does not request of them to build from source seems to not be a show stopper for the current suggested improvement, but something to consider in a future improvement via a new thread.

I do not think this is part of current UKT/UBC forwarding policy. Be that as it may, this seems not a show stopper, but something to discuss for future improvement in a new thread. On this point, one would want some upstream documentation on forwarding policies to educate ORs.

Thanks again for responding.
