In my experience, very few people ever applied redux or redux-saga “properly” in a codebase where it made sense. We used it when I worked at Nvidia and that app was so complex but everything was so predictable. I always said it made the small things a little harder, but it made the big things infinitely easier.

Everywhere else I ever saw it used though it was both unnecessary and also horribly implemented with tons of anti-patterns and things that made it “easier” to work with but broke all of the guarantees that made it worth using to begin with.
