I don't really believe this to be an issue - Valve directly contracts CodeWeavers, they developed Proton together, and they've been pretty clear from recent hiring bursts that it was specifically to work on Proton. I have to imagine the income from Valve is exponentially higher than the relative niche of CrossOver. They're basically a subdivision of Valve now.

I'm interested in alternate explanations if you have them, to be clear this is only my theory.

While Valve might make up a big part of CodeWeavers book of business now, that was not true when the original contract was signed.

The alternate explanation is that it's rather pointless to integrate it because all new Macs are ARM, and there are basically zero Windows games compiled for ARM.

Not likely considering Valve are working on an ARM version of proton in the open, have published test results for x86-64 windows games playing on proton-arm64ec-4, and there are credible leaks that the Steam Frame uses an ARM cpu.

If anything Valve is moving towards ARM and taking the library along with it.

Then it will probably happen after they get it polished on Windows.
