But observables are very different from promises at the core. Not only are they cached, but they're also eagers, while observables are not. The very minimum implementation of an observable is just a few lines of code. Promises...are much more complex. So I'm not sure how reusing operators between the two efficiently would work.
So yeah, just use observables. Most people think observables are a more complex, higher level abstraction with promises being the primitive, simple one. It isn't true though. Observables are much, MUCH simpler, and are perfectly suited to doing everything promises do, but better (lazy, optionally cached async primitive is way better).
