I don't mean I'm passing new stuff to the 3rd party hook, but that it returns a function that's usecallbacked, and hence I cannot myself use it as a dependency

I don't mean I'm passing new stuff to the 3rd party hook, but that it returns a function that's usecallbacked, and hence I cannot myself use it as a dependency in a useEffect without it triggering every render. So yeah, if you expose a function in a piece of reusable code, you must useCallback around everything and be very defensive, or you mess up for those integrating with you.
