Yes, that's exactly what we were trying to avoid.

How does this work exactly? And could it be implemented for Fedora (within the
scope of this change)?

True, but if then one BuildRequires: pythonXdist(M) is there a way to set which
minor stack should be chosen?
I.e. can we set which Minor stack would be the default per the given Major
version?

I'm not sure I understand. And how does it work with Python 3?
