I really must start posting on www-html more, instead of just reading. As far as I can tell, the HTML WG hasn’t released a good spec since HTML 4. (And that I only count “good” as it was an obvious improvement over HTML 3.2; everything since then has been stagnant or worse in terms of good design.
Also, I need to post to the WHATWG list more, too. While it’s making definite improvements with HTML 5, it still doesn’t separate documents from application UI. That makes it “relatively good” as HTML 4 was, and non-relatively probably the best spec of its type there ever has been, but still not good enough.
