I never considered that. I guess we also have a similar problem with experimental_useEffectEvent.

Not that I know of. But it might be worth handling the pattern anyway. I think we can assume we'll create more unstable_ or experimental_ prefixes in the future, beyond useEffectEvent / useContextWithBailout.

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
useContextis 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.
