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?


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