This is one of the reasons I was always a bit annoyed with WhatWG splintering from w3c. If we had bitten the bullet 20 years ago and stuck with xhtml then I think we would be significantly closer to people using structured formats for web documents by default. HTML being loosely structured was a conscious choice - not a mistake. I'm also surprised that TypeScript finally managed to sway people. I would bet a large number of people here won't even remember the whole ES4/ES5 debacle. There was a time when types (and much more) were being added to ECMA Script proper through the standards process before Yahoo and others killed it.
