Missing documentation of `dispatch` function's stability

First, I like the new React docs a lot! Unfortunately, I can no longer find the following information about useReducer that was once available in the docs:

The useReducer hook returns an array with two elements: the current state and a dispatch function. The dispatch function is used to update the state by calling it with an action object. The dispatch function returned by useReducer has a lifecycle similar to that of the component it is used in. It is created when the component mounts and destroyed when the component unmounts. The dispatch function is guaranteed to be stable across re-renders.

Is this no longer the case?

On page Lifecycle of Reactive Effects there is a note box saying "In some cases, React knows that a value never changes..." and mentioning useState and useRef. It would be ideal if the documentation would explicitly enumerate all the stable return values from hooks, i.e., the ones that share the lifecycle of their component.

Inizia dalla pagina «Lifecycle of Reactive Effects» e dalla documentazione attuale di useReducer, quindi confrontale con i dettagli sulla stabilità citati nell’issue. Traccia dove sono documentate le garanzie sui valori restituiti dagli hook e aggiorna la documentazione pertinente in modo che la stabilità di dispatch e i valori degli hook che dovrebbero essere stabili siano espliciti e coerenti.
