Have you actually verified that most of the binaries on ARM Windows builds are in fact x86_64 and not ARM?

Because I'm pretty sure that the core *Windows* software can target ARM just fine, it's all the other software people want to use that has never been built for ARM.

I'm willing to grab an ISO and validate this myself, if I can find one.
