This is really useful when working with GUIs.
For example, it can be used to implement type-aheads: https://www.learnrxjs.io/learn-rxjs/recipes/type-ahead

See the following for existing implementations in rxjs.
https://rxjs.dev/api/operators/switchMap
https://www.learnrxjs.io/learn-rxjs/operators/transformation/switchmap#why-use-switchmap.

I'm currently implementing this, expect a PR soon
