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.
