I disagree that there's an important difference.  The point of MQ is
to test for things that are outside the document itself; that's what's
meant by "the medium", as it's the context in which the document
itself is embedded.  I don't think it's important to draw this
distinction for authors.

More importantly, I don't think it's worthwhile to create a third type
of conditional rule which has identical syntax to @media, solely to
represent a dubious semantic distinction. I'd support this if there
was no good way to make safe syntax for the author-defined stuff, but
there is, so I'd greatly prefer sticking with @media as it is.
