I think a really nice addition would be an autodetect option for those
users (e.g. desktop) that know they do not want to migrate the guest
to a lower-spec machine.

That option IMHO should just show up as identical to the host cpu, with
the exception of features that are not supported in the guest.
That's exactly what -cpu host is. IIRC it's the default now.

Not yet.  Someone has to send a patch.

We can't enforce this wrt migration until someone implements migration of cpuid state.
