Well actually I think the control/option/command paradigm makes more sense than ctrl/alt/super, so yeah, I'd love this being copied by Microsoft. It's harder than just supporting Cmd-X in the Finder though. Adding Cmd-X to Finder is just a net gain, it doesn't even require deprecating or breaking anything. It just brings a standard to an app that should support it.
