What would be awesome if instead of a Rosetta-like (or qemu-user-like) compatibility layer, the chip supported multiple ISAs natively.

The only company that has the rights to do both ARMv8 and amd64 is.. AMD :)

That would be nice but NVidia got in legal trouble with x86 patents when they tried to do that with their Project Denver.

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.
