For what it's worth, I vaguely remember a working group discussion
to this effect:  that empty lists are valid according to the media
queries spec (and equivalent to 'all'), but that the @media syntax
doesn't allow the empty list form.

The media queries spec used to have slightly more prose about this,
but it seems to be gone; see
