2-23: Consider adding version validationWhile the implementation handles module availability, it doesn't verify if the loaded versions are compatible. Consider adding version checks to ensure compatibility.

14-14: LGTM: Proper error handling implemented
The error handling has been implemented as suggested in the previous review, which prevents undefined variable issues.
2-23: Verify module compatibility
Let's verify the module structure and availability in the codebase.
✅ Verification successful
Let me gather more information about the urllib usage and exports to ensure compatibility.
The module loading changes are well-structured and safe
The code changes implement a robust fallback mechanism that is well-supported by the evidence:
- The codebase has urllib v3 as a dependency, but includes proper fallback to urllib4/urllib-next when needed
- The required exports (MockAgent, setGlobalDispatcher, getGlobalDispatcher) are consistently used throughout the codebase
- Extensive test coverage exists for both urllib and urllib-next implementations
- The fallback mechanism is defensive with proper error handling for missing modules
The implementation ensures backward compatibility while supporting newer urllib versions, making it a safe and well-designed change.
