Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/52837 # Changelog [Internal] - This feature has been enabled by default for a while, and has been proven to both not cause correctness issues, and also provide tangible performance improvements. We can remove the corresponding feature flag to improve code maintainability. Reviewed By: rubennorte Differential Revision: D78978302 fbshipit-source-id: 45cb865321f6e0eb449427845772fc522221514a
