It seems more than appropriate to also cover redux-observable. It leverages ESNext observables with is significantly a better async abstraction than promises (inc. async/await) and callback-based systems.

It's also very popular to be used within React apps and redux will often also be used with libraries or frameworks that already leverage observables with significant gains over existing async abstractions such as RxJS & Angular 2 (which uses RxJS to provide observables be continuously available).

Accordingly, it made sense to mention this as a suggestion.
