They won't add async/await as a direct code instructions, but as tranlated code / pollyfill.
Like Babel does, and like TypeScript does for a lot of stuff.
A lot of browser engines don't have classes either, especially any older version.

Is that the official plan? I ask since async/await will presumably be going into the actual JS spec, so I'd expect engines to hold off adding support except behind some kind of warning flag.
