+1, we really need to get Python out of the minimal installation.

The focus should be on replacing the existing Python-based packages in the 
minimum set (e.g. yum) by native replacements (e.g. zif). Adding more Python 
stuff with additional Python dependencies is a step backwards.

I really don't understand why a core system component such as firewalld is 
implemented in Python!
