So I agree we should stop shipping 32-bit slices in our binary distributions of Qt for iOS. We should not deliberately break 32-bit support though (and it's hard to do this accidentally anyways).

But as long as developers can keep enabling continued use of those devices somehow rather than sending them promptly to the shredder as soon as Apple wants you to, I think we should support them in their efforts, or at least not interfere.

Removing 32-bit support from our packages only drops the iPhone 5 from support by Qt. The 5s and above are all 64-bit so this has been a long time coming.

I'm all for dropping 32-bit "support" (from the CI). If people REALLY need 32-bit, they can go compile it themselves.

Apple gets a black mark in my book for trying so hard to remove that choice.
