Summary:
Minification is not needed for hermes as it does all required optimisations on the bytecode. This is what facebook does internally for hermes bundles and I also validated by comparing the bytecode bundle size on a minified and non-minified bundle.
## Changelog
[General] [Changed] - Don't minify JS bundle by default when using hermes
Pull Request resolved: https://github.com/facebook/react-native/pull/30496
Test Plan: Verified that the JS bundled generated on Android and iOS when using hermes is not minified by checking the generated JS file manually.
