I am a developer. Due to binary incompatibility between
framework-13.10 and framework-14.04 and differences in the Qt, I need
to upload 4 clicks for a version of the application:

* armhf for framework 13.10
* armhf for framework 14.04
* i386 for framework 13.10
* i386 for framework 14.04

Are you expecting for me to ship 4 binaries inside a single click,
when only one of them will be executed on the client machine and the
rest are unneeded cruft? If that is the case, my application size is
balooned artificially 4x, and thus is pushed above a threshold one
would choose to download over 3G for example or worse not install my
app at all.

What's the app developer story / plan here?

I thought we will support one version of the app per ( framework X
arch ) combinations.
