What makes you think Apple cares? Most serious gamers would already be dual-booting Windows if they want to game on a Mac, and most casual gamers presumably wouldn't consider it a dealbreaker to have older games stop working.
I'd say serious gamers already switched from macOS to Linux if they don't want to use Windows to begin with. Simply because you can run DX11 games in Wine on Linux, but not on macOS. Borking 32-bit games would only accelerate this shift.
Sincerely, A person who uses MacOS and games on a console.
