This is experimental-only and FB-only hook. Without these changes,
inspecting an element that is using this hook will throw an error,
because this hook is missing in Dispatcher implementation from React
DevTools, which overrides the original one to build the hook tree.
One nice thing from it is that in case of any potential regressions
related to this experiment, we can quickly triage which implementation
of `useContext` is used by inspecting an element in React DevTools.
Ideally, I should've added some component that is using this hook to
`react-devtools-shell`, so it can be manually tested, but I can't do it
without rewriting the infra for it. This is because this hook is only
available from fb-www builds, and not experimental.
