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

I think I more or less agree with you.  However, when you look at MQ,
literally the only things you want to decide on are width/height, and
*maybe* grayscale/color. You really don't need to be generic here, so
you might as well optimize the syntax to make it easier to type.

I think this is too much, personally.  I'd prefer more verbosity here, like:

<img src=foo.jpg srcset="foo-big.jpg min-width:1000px, foo-big@2.jpg
min-width:1000px 2x">

Importantly, I think I'd like to be able to use either min or max, but
@srcset's microsyntax only talks about min sizes. (I got it wrong in
my previous email.)
