That would be a weird choice, because it's not actually the default!

The obvious analogy here is with -cpu best, -machine gic-version=best,
etc -- use "best". You can argue that it's maybe not got the ideal
set of connotations, but I think that trying to be consistent about
the name we use for "do the thing that seems to be the most
sensible for the host/etc that we've got" is worthwhile.
