I'm generally in favor of "embracing the host" but both generators and async/await would probably require substantial rewrites of core parts of the compiler. It it not just about adding a small *** or *async* keyword somewhere. The compiler will generally emit anonymous functions at various places to ensure proper scoping and this can pretty easily break async/generator functions. Given that you'd emitting ES6+ anways however you could replace those with proper block-scoped lets though. Of course that is not a reason to not do it, just don't underestimate how much work this would be.
I certainly looks like the JS world is adopting async/await but given the rate of change in that ecosystem that might change again when the next thing comes along. Given that the React folks decided to implement a pretty substantial feature based on throwing promises I guess they are here to stay for a while though. I do not think that this compares in any way to core.async however. It is a much more powerful abstraction which can do a lot of things async/await can't and anything that does can easily be achieved with core.async and a few helper functions/macros. Yes, core.async is not perfect either but someone could work on fixing the kinks. I guess I agree that we should eventually support async/await + generators for the sake of full interop but not because of "issues" with core.async.
