I've found several "subtle" benefits from hooks in the way they can influence more idiomatic code structure, for example "code smell" becomes more intense and dictates more actions because when a function is > 100 lines of code it sticks out like a sore thumb. It's also influenced us to put more business logic into redux where (arguably) it belongs.

My coworker showed me that hooks are just functions, so you can still pull apart your functional components hooks into a bunch of imported or defined functions.

Of course that doesn't help if you're still pulling in a lot of hooks, since it's 1 line per hook minimum.
