- React 19 Symbol Detection: The
isReactElement()changes appear correct - Rollup Plugin Migration: Successfully migrated from closure-compiler to terser
- VisionOS Implementation: Well-documented utilities with comprehensive features
- VS Code Workspace: Properly structured multi-root configuration
The PR represents a significant modernization effort with comprehensive documentation and testing (176 tests, 165 passed, 11 skipped as noted in the description). All changes appear to maintain backward compatibility as stated.
