On top of that, Google is now requiring that you keep within 2 versions of the latest API, meaning that you have to reupload your app every 2 years (or less) to keep it on the store. Even if it's completely fine.

I think there's something similar for Apple, but I can't actually remember the details right now.

Apple doesn’t generally enforce lower bounds on the supported OS or SDK built against unless there’s recently been a major transition (e.g. 32-bit support being dropped), which don’t happen too often. They will remove listings that have sat idle for too long though (4-5+ years I think, but don’t quote me on that). I’ve never dealt with it personally since the projects I’ve been responsible for have always been getting updates.
