Microsoft has been known to do things half-heartily on both h/w and s/w: phone OS, Windows RT, UWP, app store, etc. Even the Internet Explorer to Edge transition was long overdue, but not too late. The way MS works is very much like Google where they have their cash cows and everything else seems like a diversion until they miss the boat on a new thing and it's too late. Remember that Windows NT originally supported x86, MIPS, Alpha but haven't taken it further. They also make entire toolchains that could make building for multi-targets as seamless as they choose save final validation.
