You can look at theoretical process improvements all you want, but the reality is that the WHATWG process has driven Opera and MS out of producing core web browser tech alltogether, and prevented countless unnamed innovative browsers from being even considered, let alone developed, out of sheer infeasability to develop a browser from scratch. Worse, it doesn't help that the WHATWG "living standard" process is setup to never end, and never produce a final spec of sorts, contributing further to the problem.

WHATWG fails to realize that they cannot represent the browser vendors left (Google and Google-financed Mozilla) having a desire for ever more webapp contamination, and web users and authors at the same time who want a stable content media format.

Also, I have to say your comment doesn't sound very promising wrt the future WHATWG/W3C relations being anounced.
