Google controls JS to the point of being able to ignore the spec (e.g. that time they left TCO behind an experimental flag and it just went away despite being in the spec). As long as node and chrome are so dominant, we're probably not going to see big shake-ups in JS that aren't driven by Google themselves. JS is flexible, you can cover up a lot with polyfills, but not completely different syntax. Doing that without Google's buy in would create a rift in the internet that would either end with browser specific web pages, or with the complete loss of power for the committee that sets the ECMAScript spec as JS officially goes from being a language that is defined by a spec to a language defined by a canonical implementation (in this case V8).
