Important to note that this is different than what Codeweavers did and the timing of both their announcements is purely coincidental.

Apple did contribute to the Wine codebase and have their own translation layer.
Performance and compatibility seem to be much better than what Codeweavers showed which is expected given the translation appears to be DXIL to MSIL instead of DX to VK to MS.

This is also a triumph for open source imho because wine is now receiving patches for macOS directly, and it’s a symbiotic relationship that hopefully grows.
Things look very promising.
It's Wine with some special sauce (Apple couldn't reuse VKD3D because they chose to invent Metal rather than stick with OpenGL/Vulkan so they had to build their graphics translation themselves). Crossover is built on the same technology. In fact, Apple's brew script literally links to Crossover's sources: https://raw.githubusercontent.com/apple/homebrew-apple/main/...
Things like the crypto API should be implemented if you can find the reference for your specific API calls here: https://github.com/wine-mirror/wine/tree/master/dlls/crypt32
Apple's version of Wine is aimed at developers, though. It shouldn't take too long for someone to make an app or script to easily set up environments with the developer runtime, but I doubt they'll support it as well as Valve supports Proton. If your application of choice doesn't need any fancy graphics, there's a decent chance Wine/Crossover can already run it anyway, no need to mess with Apple's SDK.
With the M2 Max outputting 28fps at 1080p (screenshot linked), I wouldn't expect too much from the gaming performance of this thing, though.
It's still not a great thing to do. Apple used to contribute a lot more, even if some of their stuff was exclusive to their platform. https://opensource.apple.com
macOS runs x64 executables just fine through Rosetta so I don't see why Wine couldn't make use of that hardware acceleration.
It's also possible to only simulate the entrypoints through Rosetta and then execute native aarch64 code from there. On Linux https://github.com/ptitSeb/box64 does exactly that, for example. However, with the performance Apple has been able to squeeze out of Rosetta, I'm not sure of that workaround is even necessary.
