I've only seen javascript-based implementations. I've also not seen any commitments from any browser vendors to implement either specification.

The reason we have not been able to merge the two is that srcset is specified in such a way that it is tightly bound to HTMLImageElement (meaning we can't reuse it with <source>); and the source element is tightly bound with media elements (audio and video), meaning we can't use it with <picture> without rewriting that part of HTML5. Because of the way HTML5 has been written (there is always an explicit tight coupling between algorithms, concepts, and elements - which is great for clarity), there is no simple way to reuse components from HTML5 in extension specifications such as <picture>.
