There is a ton of history and valuable conversation around this topic already in the Community Group, and we’ve been working with a couple of browser reps trying to get this thing solved. We’ve even gone so far as to put the solution that seems to have the most legs together as a sort-of spec, so all the details are in one easily-parsed place: https://github.com/Wilto/respimg

The Responsive Images work is intended to solve a different issue than
the "send high-res versions if you have the screen and bandwidth to do
so".  It's for serving different images based on various MQ
conditions, just baked into HTML markup rather than hacking it in via
backgrounds.  MQs, though, are a fundamentally unsound method for
doing bandwidth-responsive image serving.  I gave the basic example of
why it fails in an earlier message in this thread.
