There was a problem hiding this comment.
In theory these __DEV__ flags shouldn't be needed since every usage of this flag should also be wrapped in __DEV__. Otherwise, when we remove the flag, we might have missed to wrap it.

@bvaughn does this turn Strict Effects on even outside of StrictMode? It looks like for strict effects, we only check the feature flag, instead of checking the mode on the fiber? |
