True. But we say that queries involving unknown media types should be
false. E.g.:

  @media 3d-glasses { ... }

I assume we all agree that this should be false.

Logically, it follows that "not false" is true. 

I think this is an edge case that will not cause much problems in real
life. So I suggest we keep the spec as simple as possible and do not
make exceptions in this case.
