There was a problem hiding this comment.
Since enableStrictEffects used to be set to __DEV__, does this mean we flip this flag in prod more often (here and in other places where there's no __DEV__ check). Does this matter? It seems good for consistency to always set StrictLegacyMode together with StrictEffectsMode but I want to make sure there's no accidental assumptions about which flags are DEV-only.
There was a problem hiding this comment.
I don't think it matters. StrictMode itself has a check to see if __DEV__ is true or not. So even if this flag gets flipped more often than before, it will not cause StrictMode to be triggered in prod.
I'm trying to reduce complexity around StrictMode, it seems unnecessary to have several flags controlling it, we want to behaviour to be consistent.

The plan for RN OSS, is to resolve last StrictMode violation in React Native's core components and then encourage people to start using it. |

enableStrictEffectshas been shipped everywhere except React Native OSS. Let's ship it to get consistent behaviour of StrictMode and remove unnecessary feature flag.
