The general emulation community is still working on it.
Like I was saying, if they can run retrocompatible games on Xbox Series X, a x86 Windows-like system, then internally Microsoft does have some sort of solution for running OG Xbox and 360 already working.
So it's not a technical issue, public Nintendo emulators don't really change that. Meaning that it's not any more likely that they would offer Nintendo games on PC if they owned them.
