Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/34446 I'm adding another class to the .defaults package. This will take care of setting the RootView with Fabric enabled/disabled as well as controlling concurrent root. Changelog: [Android] [Added] - Introduce the DefaultMainActivityDelegate to simplify enabling/disabling Fabric for new apps.
