The specification had recently undergone a significant simplification. The latest version can be found in http://picture.responsiveimages.org/

As a result, the above change description is no longer accurate.

A better description of current proposed API surface change:
* The `srcset` attribute will be extended. It would be able include resource dimensions, as an alternative to DPR.
* The `sizes` attribute will be defined, enabling the browser to calculate the appropriately sized resource needed, before layout is calculated.
* The `<picture>` element will be defined and used (with its child `<source>` elements) for the child `<img>`'s resource selection.

According to the new specification, `<img>` remains responsible for displaying the actual image, so previous concerns regarding `<picture>` requiring duplication of img's layout tests were addressed.


Is the WebKit project interested in accepting patches for this feature?

Thanks,
Yoav

P.S. CCing Maciej since he reviewed the spec on WHATWG
