I would like to suggest the idea of adding support for
hierarchical comps groups to Fedora.

(I'm not going to contribute actual work on this anyway, but) do we actually need that complexity?
 
The idea is make yum groups in comps more modular,
ie groups could require other groups not just packages;
at this time I don't think it would require any GUI changes.

So the proposal is not to show them as really hierarchical, and not to add any structurally new user-visible features[1] just to avoid repetition in the comps file?

Would it be an option to use an XML entity for the duplicated parts, or a similar preprocessing step during generation of comps.xml, to create the current group format instead?  That would have the advantage of not having to adjust yum/dnf/anaconda to support the new feature.

[1] Having more groups available is certainly a feature, but not "structurally new", i.e. it keeps the existing usage model.
