Adding new uAPI and new exports to eliminate one line of userspace code is not a

Well, then that's your call.
Yeah, that simplification is really minor. With this, I would rather
think KVM wants enforcement before relaying the request to the host.
That enforcement is unthinkable without supported_xcr0. But it looks
like userspace is somehow trusted here for KVM.
