And the super heavy js websites will work?

Not necessarily.

How old and how backward compatible are you thinking?

- Symbol is 2014-2015

- Map is 2014-2015

- Weak* data structures and their methods span 2014-2021

- WebGL 2.0 is 2017-2021

- Custom Elements are 2017-2021

- Chrome-only non-standards (hardware APIs and a bunch of others) are pumped out at a rate of up to 400 per year

- WebAssembly MVP is 2017-2018

And so on. That's off the top of my head. None of them are backwards compatible. Some of them cannot be polyfilled.
