Modern HTML browsers have become Swiss Army Spaghetti. Perhaps we need to split the standard into smaller components so one size doesn't have to fit all. I suggest at least 3 sub-standards:

A) Document-oriented standard. Perhaps HTML standards are "good enough" for this?

B) Media/Art/Gaming.

C) Business & Data CRUD/GUI

(And don't link that XKCD cartoon about 15 standards. There are zero for these categories.)
