But this is kind of my point: As of now, this doesn't exist.
I don't think the commit history works. It doesn't give you any indication about which changes are relevant or irrelevant and it doesn't tell anything about the larger efforts taking place.
Actually, I don't think it would even make sense to create an equivalent of the W3C diff, because there are no versions or other structures to organize the changes around - there is just a constant stream of changes. (Which is kind of the point of the living standard concept after all)
The W3C fork's versions are arbitrary too though (yearly). You could organize a yearly update on what's new in the HTML Standard if you thought that would be valuable to people. It wouldn't change the fact that browsers release new features based on the ever-changing standard every six weeks. But it sounds like at least some people would find it useful.
Personally I'd tend toward weekly or monthly, although I admit that yearly is more likely to generate HackerNews posts ;)
