With modularity, we have a lot of flexibility about not shipping artifacts that we don't expect end users to actually need/use. For example, filtered rpms, buildroot-only modules, etc.

However, this introduces an inconvenience for many packagers (and, occasionally, users). You sometimes need to reference/find/review/etc those rpms and modules that are "hidden" from the compose of the OS.

As a result, this ticket is to develop a document outlining what a new repository would look like, how it could get produced, and what it should contain (or, what use cases is it satisfying). At a minimum, it should address the points above.
