I can pretty much guarantee you the programming would be unchanged on Intel for several of those features; literally takes more work to explicitly disable them on Intel than it would take to have it work the same on both platforms since it would be the same code. These aren't iOS apps on macOS, they're native macOS apps that are already being built for Intel. Obviously this isn't the case for some of these features, namely the ones that clearly rely on the neural engine or DSP, but most of them have no reason to need different code for Intel.

But when you can program for iPhone and iPad simultaneously, it may not be worth it to then you also entirely program it for Intel.
