Most of the original x86_32 patents have now expired, that was sufficient to let Microsoft build the emulation layer for WoA.

It might be more feasible now, except in the last ~5-10 years there's been a push to make many PC apps x86_64 only (e.g. Ubuntu dropping i386 support), so the benefit isn't quite as wide any more.

Do software implementations have to care? qemu implements like every ISA out there..

Presumably so, or Microsoft would have extended the WoA compatibility to x86_64 as well.
