Just ran into this when building a component to display and filter data. It was starting to turn into a monster when trying to use Rx.js and in the end, the code was simpler to understand with multiple for loops and forEach and map/filter calls.

I ended up with a service that doesn't rely on observables.

Not to mention, easier to test. I had a branch of my code where I had finally figured out how to reliably test the stream/observable variant, but it was just an ugly mess.
