Well, the GP was talking about getting wine to run. Your examples cover either instruction set emulation or ABI emulation, but not both. In order to get wine to do something useful om ARM mac, it would need to do both while somehow being optimized to not suffer too much performance loss, and without suffering too much compatibility loss.

It turns out such a project actually exists![0] But it seems to be in an early stage, and relies on infrastructure not exactly favoured in MacOS (QEMU, deprecated OpenGL). Apple could work to port it and polish it so it works with most apps, but why on earth would they invest so much in Windows compatibility?

IMHO, Apple has two reasonable choices here: Ignore Windows compatibility from now on, or do just enough so that Windows on ARM boots, and let Microsoft deal with the supporting x86 Windows headache and blame.
