It’s sad but like… the costs of maintaining a platform to keep everything running indefinitely are not worth the advantages unless your entire business depends on it. That only applies to Microsoft, and even then, no one has a contract with Microsoft guaranteeing that their focus on backward compatibility will continue indefinitely. All anyone has is faith based on 27 years of consistent behaviour.
There are some interesting developments on Catalina right now that have restored support for some apps that shouldn’t be working anymore and given the little I’ve looked at it, it’s possible some of this could be ported over to jailbroken iOS devices given the shared foundation? But there never really was much effort being poured into backward compatibility work in the scene while I was a part of it, and most of the brightest minds have left the scene, so there’s not too much hope there. The best you could hope for is some kind of translation layer that lets you run ARM builds of iOS apps on top of historical versions of Intel frameworks in the iOS Simulator, but then that would be with keyboard and mouse, and iOS SDK versions are only running on specific versions of the Mac OS too…
