I think I'm a bit confused on terminology here. I don't think of selectors
as allowing commas. I think of that as a selector group as per
http://dev.w3.org/csswg/selectors4/#grouping.

Terminology aside, I don't think many web developers think of a
comma-separated list of selectors as a single selector. Similarly,
querySelectorAll doesn't take a comma-separated list, right? It would be
nice if it did, but I think that ship has sailed.

Boris, Rob, you have opinions on this? I don't feel strongly about this. I'm
not opposed to changing WebKit if Gecko changes as well, but I still prefer
:any to :matches.
