This is somewhat true, but where do we stand a decade after we got HTML5? Most browsers use Webkit/Chromium under the hood (because nobody wants to compete in the race anymore), and building a new browser from scratch seems impossible. I wonder if there is a causality between ditching versions and browser vendors exiting the development of their own engines.
