I agree with your main point. But want to clarify that Proton/Valve is NOT an emulator. As such the games people play on Linux run at the same speed/performance than in Windows. Proton is based in Wine I Not An Emulator. Which basically is a set of "library that is cross platform by design" . Its doesn't add the additional emulation layer . The problem currently is not the technology: AFAIK Unreal,Unity and other libraries already offer builds for different architectures. The problem is operational: Having to maintain/support/operate an additional architecture.
