No, I am talking about RFC 7950, which defines the concept of implemented module. If imported features are ever to be restricted only to implemented modules, then it requires a new YANG version and cannot be done via an erratum.

Tools may - and indeed do - use different methods for specifying the overall data model, including the implemented/import-only status of modules.

Yangson happens to use YANG library per RFC 7895 for this purpose, and features work the same for modules with conformance-type "implement" and "import".
