Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/43070 **Context** The `codegenNativeComponent` function is a hint for the codegen that the file that contains it is a Native Component spec. Static ViewConfig codegen overwrites this function call by the generated ViewConfig. If this function is not overwritten by the codegen, it has runtime behaviour that falls back to `requireNativeComponent`. At the time when this system was built `requireNativeComponent` was not supported in Bridgeless mode because it is relied on some Bridge-only functionality. That's why it outputs error in Bridgeless mode. --- This is not the case any more, we now have interop layers which provide the functionality needed by `requireNativeComponent`. The SVC codegen is implemented as [Babel plugin](https://github.com/facebook/react-native/tree/main/packages/babel-plugin-codegen). The are scenarios when it is not run for the native component specs: - If the plugin is not used for whatever reason. - If Babel is not used for whatever reason. In order to not to regress the DevX for such cases, we've turned the error into the warning. **Note:** we use `console.info('⚠️...` instead of `console.warn('...`. That's because `console.warn` also prints a stack trace in the console, and we didn't want to create too much noise. Changelog: [General][Changed] - codegenNativeComponent show warning and not error if not code generated at build time.
