I think it's a nightmare for trivial projects too: it's like building a star destroyer for a todo app, because, you know, one day that todo app may end up being the death star. Who knows. Gotta be ready for that. Another thing: debugging RX. God, it hurts. Like Alice in wonderland. I worked with an rx guru on my last project and while the code was beautiful, huge and complex, showing a load indicator or handling simple ajax errors, doing persistent navigation states (and hoping that the back button would not break the application) were just omitted altogether. It was an engineering marvel, and a usability trainwreck with around a six megabyte initial payload and no lazy loading at all.
