[whatwg] So if media-queries aren't for determining the media to be used what are they for?

Hm, I'm confused.  The "NNNw" and "NNNh" parts of the microsyntax are
precisely intending to solve the (1) case.  They're more-or-less
equivalent to using min-width and min-height Media Queries.

Looking through the list of Media Queries, it seems that the only
useful ones for art-direction style changes are the width/height ones,
and maybe the monochrome or color ones.  We can always add the latter
to the microsyntax if necessary (their syntax in MQ is pretty weird).

I'm not aware of any plans for future MQs that would be very useful here either.
