Couldn't Apple spend their resources on that? Proton is open-source, and Apple's the one with the incentive to have more "prestige" AAA game devs to parade around during keynotes.
It's textbook "perfect is the enemy of good" because yeah, compatibility layers have overhead, native is better, but if you insist on native everything but can't get devs on board then you just end up with no games.
Compare Steam Machine (2014) to Steam Machine (2026). The difference this time around is Proton support, and you can pretty easily see the hype on the internet for the new version, even after the original version was mocked relentlessly in some circles for having "no games."
Also, how could Apple kill the old software that is better than the new, if it doesn't control the emulation? This way they don't have to even have 10% of the features to force you to buy again.

The efforts are usually short-lived and mostly fruitless, but I wouldn't say they're "grossed out" by gaming nerds.
They released Apple Vision Pro with no ability to play popular PC games on it.
A VR headset. That doesn't play games.
"evaluate your unmodified Windows executable on Apple silicon using the evaluation environment for Windows games"
A bunch of games just ship the Windows executable and some version of that translation layer in their MacOS App bundle
They'll spend billions on a handful of (late) AAA ports for macOS every 4-5 years, and then go radio silent again.
