Yesterday I made a similar proposal in an other thread:
http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2012-May/036143.html

I'd like to suggest that @srcset in this form would also be suitable for 
the <img> element, to address the optimization use case (without art 
direction) without the verbosity of <picture>.
