Can you explain why? I believe the RICG's identified use-cases are
both reasonable and minimal.  If we address *only* the density case
right now, significant fractions of *existing* responsive images code
won't be able to migrate to the standardized solution, and will be
stuck with hacks.

We'll obviously never be able to satisfy 100% of use-cases, nor is
anyone trying to.  But just density isn't enough, based on the
observed patterns in the wild.

The RICG and related community has agreed on src-N, and the relevant
Blink and FF devs have as well.  The only holdout is WebKit, but they
haven't expressed any technical objections, just aesthetic ones.
(And, not to be rude, but I don't trust the aesthetic judgement of C++
hackers when applied to the web platform; at least, not over the
judgement of actual JS and HTML hackers, who are generally fine with
the look of src-N.  People who write the web rather than write *in*
the web have a long history of liking terribly-shaped APIs because
they're more familiar to C++ coders.)  (IE hasn't expressed an opinion
one way or the other, as usual.)

I believe you're applying an inappropriately high standard of required
agreement to this proposal, compared to what the usual required level
is for something to be accepted.
