I wouldn't do that.. Defaults are for those who don't care about setting it, or
want something that just works, by default. It's fine not to provide a default
machine type if we decide there isn't a clear win, just like arm, but IMHO
removing it just to restore it later in order to educate people makes a very
poor experience.
