While I'd love to see this happen, I'm not even sure where I would begin. But if someone out there has experience working with whatwg or W3C on these kinds of things and wants someone to help out, I'd love to be a part of it. But like you said, the hardest part is getting the different browser engines to promise support (or even take it seriously). I remember reading on HN a post from a woman who was involved in trying to get SVG in the browser standardized (sadly I can't seem to find it any more!), and just reading about the struggles she went through to even talk to someone involved who, while receptive, basically told her that it wasn't going to get done. It seems like there would need to be an "advocate" who is part of the teams on EdgeHTML and Gecko that would be willing to fight for it before it would even begin, otherwise, like you said, it would all basically be wasted effort. The JavaScript standardization system is quite nice, I wish that browsers could get together and come up with something similar for Web APIs...
