New Features
What is the new or updated feature that you are suggesting?
The second argument of useDebouncedEffect, useThrottledEffect, etc. is DependencyList which only accepts an array, but it should also accept null or undefined when the effect should intentionally run every render (well, potentially run every render and potentially after a delay, given the debounced/throttled nature).
Why should this feature be included?
Because React's own useEffect and useLayoutEffect support it, and it can be quite useful!
