I'd be happy to help design a new list for Fedora, if we decide to go
down this road.

There was a proposal in RPM upstream to add a concept of "tags"/"meta
tags", which could be a set of properties that an RPM could be
categorized under. However, the idea was not fleshed out enough for us
to seriously consider it as something to support in RPM.

However, I'm not sure multi-categorization makes sense beyond setting
up installation groups.

This is where I think that transforming comps into metapackages would
probably solve the remaining issues we have with the current workflow.
