Done

This seems like a somewhat general problem between explicit attributes, implicit attributes, and attributes added via the pragma. It might not be worth generalizing yet, but I'm curious to know whether we'll need this for things like visibility and type_visibility as well.

Possibly. We haven't come across a use case that requires that yet, but we would be definitely willing to work on a more generalized solution in the future if such a need arises.
