Apple Silicon has special support for running ARM code with the "Total Store Order" memory model of x86.

JIT-compiling emulators for other ARM processors otherwise need to be stuff the code full of memory fence instructions to be able to utilise multiple cores properly. Optimising those away can be hard.

Not really though, it's just another layer which isn't wine. They might put effort in to help Rosetta translate, but wine is not an emulator.

I think some bits got added from the point where they got Wine working on OSX PPC back in the day.
