Windows on ARM was already very decent on virtualized Apple Silicon, running x86 binaries without much fuzz, they sure have been working on it in the background ever since Windows RT.
At work, there are some SAP development functions that required Windows, so people with MACs would beg, borrow and steal to get Windows on their MAC inside a VM. Apple's 'M*' chips ended that.
That was R/3, I do not know about the new version of SAP. I would think they would fully support Apple with that. But you never know.
Meanwhile Microsoft ships apps that don't work on ARM, like Flight Simulator.
