alt Hacker NewsNT shipped with USC-2 as UTF-8 (and -16) did not yet exist. USC-2 naturally translated to UTF-16, hence the choice. NT/Win32 is also designed for fixed-with code units, something UTF-8 doesn't support.
You can use UTF-8 on a per-application basis, within limits.

Conversely, UEFI is UTF-16 only, thanks to Windows.
UTF-8 only would be an ABI breaking change, so that's not going to happen. We don't want the NT kernel to end up like Linux, after all :-)

I think you're making a joke, but it still doesn't make sense. Linux does avoid breaking changes to its userspace ABI
