I believe the official recommendation since hooks were announced is to omit the array unless you need it. It makes things much easier to reason about, and many effects can run on each render just fine. It's mostly[0] a performance optimization. Oftentimes you'll want to make an additional comparison between previous and current props to decide if you actually want to do something anyway.
[0] Possibly entirely. Remember that useEffect's goal is to synchronize with an outside system. Additionally, while I can't find references for a similar thing in the docs for useEffect, for useCallback and useMemo the dependency array is explicitly not supposed to give any semantic guarantees about when the value will be re-memoized. React is free to "forget" values if it wants and re-memoize when needed.
