I get what you're saying, but what I meant is that it's surely possible to keep the current features while streamlining it into something coherent, much smaller, and easier to implement. The modern web platform's bloat and what you can achieve with it always reminds me of 1990s demo scene mags on floppy disks and their mag engines. I think most of the problems stem from adding more stuff to HTML rather than taking what we build today building the smallest possible DSL and its engine around it. At some point we have to do a cut like that or we'll have browsers that'll have to support many, many HTML profiles and become monstrosities.
