Make it a requirement in order to ship a new version, developers would do it in an instant. Just like they did with 64bit builds.

Sure, a small number of apps would fall to the wayside. But it’s not like Apple has hesitated to do that before.

I think you are grossly underestimating the number of apps that no longer see regular updates/have active developers

I think you’re grossly overestimating how many of those apps are actually used regularly. Even if Apple only got 15% of the entire App Store available on x64 it would fulfill the needs of almost all users.
