I hope it does get fixed, but Apple actually has a bad track-record with another deprecated API, AppleAL (OpenAL). They broke it in a very interesting way in Tahoe where mono-channel audio on Aarch64 (not through Rosetta) did not play and it was broken through all the betas. I believe it actually may still be broken today. The workarounds were either mono-to-faux-stereo channel duplication or switch to openal-soft.
OpenGL is an even bigger deal so I don't see a world where it doesn't get fixed, but I also thought exactly the same way with the previous issue. It seems that Apple does not have any older video games in their testing apparatus.
OpenAL was terrible on Android as well, but audio on Android was terrible at the time anyway. Game developers had issues like explosion sounds playing half a second after the visual effect. Google made excuses for years saying it’s not their fault somehow, while it was fine on iOS, before they eventually fixed a scheduling mistake they introduced.
