Notes:
- The 'USE deps' column lists whether the flag was used in any USE dependency for any of the implementations. It also states whether the dependency had a USE default.
- 'Always-on' modules were either based on deps or test used installed implementation.
- IPv6 support was tested through using low-level socket module to connect to IPv6 service.
