Does `dispatch` function identity change when passed in context? [Re: eslint-plugin-react-hooks]

Issue:

• The docs for useReducer suggests omitting dispatch from the dependencies list of useEffect and useReducer.

  Note
  React guarantees that dispatch function identity is stable and won't change on re-renders. This is why it's safe to omit from the useEffect or useCallback dependency list.

• The docs also recommend passing dispatch function from useReducer via context to avoid passing callbacks down a large component tree:

• eslint-plugin-react-hooks warns if dispatch (that's been passed from context) is not added to useEffect dependencies list.

  This conflicts with the first point above (docs suggesting omitting dispatch from the dependencies list)

  React Hook useCallback has a missing dependency: 'dispatch'. Either include it or remove the dependency array.
  

Is this:

• Expected behavior after passing dispatch through context - so the docs should have a small amendment for this scenario?
• Or a bug in eslint-plugin-react-hooks?

Thanks for the help!!

Working Sample:

• Example Sandbox: https://codesandbox.io/s/vnq10rmwjy

Lies zuerst die verlinkte Dokumentation zu useReducer und zur Hooks-FAQ, reproduziere dann die Warnung im CodeSandbox und vergleiche sie mit dem Verhalten von eslint-plugin-react-hooks. Die Aufgabe ist abgeschlossen, wenn festgestellt wurde, ob die Dokumentation eine Klarstellung benötigt oder das Plugin-Verhalten eine separate Korrektur erfordert, und die entsprechende Schlussfolgerung festgehalten wurde.
