Comment:

 As I said in #core @
 https://wordpress.slack.com/archives/core/p1475752552004667 I don't think
 this is really going to be viable for core inclusion.

 Conditionally loading JS based on media queries seems like something
 that's either best done by a helper script (even using
 `wp_add_inline_script()`), or as a feature detection within the script
 itself on whether or not to spend time executing certain procedures.
 One big question in my mind, is what happens when the window resizes? or
 rotates as in mobile devices, are those scripts then loaded at that point
 in time? What happens to existing ones which matched the query, but no
 longer do?

 So although I like the suggestion, as long as browsers don't natively
 support it, I think it's best left up to the JS itself to handle
 conditional loading.

 I'm going to mark this as `wontfix` for the reasons above, even though I
 like it, hopefully one day either this sort of thing won't be needed, or
 browsers support it natively.
