Observables and async iterators are not at-odds. The two proposals complement each other and address two sides of the same coin (pull and push).
I'm also not sure what "headway" means here but a few months ago the observable counterpart to using the `async for` loop - the for.. on loop proposed by Jafar has been (possibly temporarily) scrapped in favor of async iteration with async iterators.
