Optional means sometimes. Intermittent functionality means confusion. 
Also, for this to be useful, the notifications would have to stay on 
screen permanently. Otherwise, you still wouldn't be able to interact 
with it unless you reacted quickly. Thunderbird has or had this. I hated 
the way it made me feel like the computers property. "Stop everything 
you're doing right now, because you only have ten seconds to comply with 
this notification". I was just waiting for it to tell me something like 
"This user has performed an illegal operation and must go to bed 
hungry". Not good! :)

You get a notification which does not require nor accept any actions. 
However, directly above the notification, you have a permanent reminder 
that there is something to react to. Click it, and you'll see a list of 
recent notifications and clicking it will show the appropriate 
application in the appropriate way. So the feature is actually there, 
only implemented in a less obtrusive way. If you're been away from your 
keyboard for a while, then you can click once to get a full overview in 
a list and react to the things you like, instead of having to close lots 
of notifications.

That something happens infrequently is probably _the_ biggest problem in 
IT. "I clicked the search field in Nautilus and then my system 
restarted". Because the notification was that you needed to reboot for 
the updates to be installed. But because that would happen so very 
infrequently, the user would never get that answered and the bug would 
never be closed.

You shouldn't choose between them. When you get an email, then you 
should get a short notification that doesn't accept any action, and you 
should get a permanent indication that both accepts and invites the 
proper actions.

I don't really understand what you mean by intrusion in this context. 
You're supposed to add those statuses for apps, but they're statuses you 
look for. You can press and hold super to get an overview. How far have 
that file copy process come, how many unread emails to I have, how many 
updates, how long until the update is complete, etc. So they're not not 
notifications, they're not indications, but they're statuses that you 
actively look for. In  other words, these are four separate ways of 
displaying information.

I think the urgent window would be opened first. At least I think that 
should be the case.

Yes, the whole point of making the notifications that way is that you 
get notified, but you continue to do what you're doing, so it's only 
presented for a short time and goes away. You can't click notifications. 
The clicks will go to the app underneath. The indicator is there so you 
don't forget. That's where you handle the thing that's happened, but you 
do it when you feel it's right to do so, not when the computer tells you 
to.

Absolutely, and that's what the keyboard is for. Press F10 to focus 
menus, navigate with arrow keys and activate items by pressing enter.
