I don't strongly object to 'max' including deprecated features,
but I do definitely object to 'max' including by default any
experimental (x- prefix) features. Those should never be
enabled (whatever the '-cpu foo' name) unless the user has
specifically opted into them: that's the point of the x- prefix.
We need to be able to tell from the command line whether it's
got any non-standard weirdness enabled.
