There are about 6 proposals related to improving the management of ports:

• Records with Directional Subtypes
• Packages as an interface construct
• Interface Construct and Port Mode Configurations
• Add "Bus" mode for bidirectional port signals
• Protected Types with Public Signals
• Protected Type on Entity Interface - This proposal

It would be worthwhile to derive generic requirements for port/interface management instead of looking at them in isolation.
