I think it’s going to be important that this be posed as a means of providing
alternate sources for *content* images (
http://www.bostonglobe.com/magazine/2012/07/22 or http://www.apple.com, for
example ). A banner that displays different decorative banners would be most
appropriately done in CSS -- this would likely be simpler for the authors as
well, especially given the new `img-set` CSS syntax. I’m sure we’re apt to see
`picture` used incorrectly for decorate images but no more than we already see
with `img`, I wouldn’t think.

It doesn’t hurt our case that this is such a high-profile issue in the dev
community, and that `picture` is likely to see use from advanced and highly
visible developers right away -- I think we’re likely to see a number of great
examples of `picture` usage springing up almost immediately, paving the way for
responsible usage in the future.
