BTW this is scholar example of use-case for Modularity.
No, this is actually exactly the scholar example of NON-use-case for
Modularity.
As others have already explained, you just cannot replace Python with an
older version from a module. That will break the entire distribution. Even
DNF will stop working, unless you rebuild that too. But rebuilding all the
Python packages in Fedora against the old version just does not scale.
This is the scholar example of use-case for parallel-installable
compatibility packages (python3.7 and a python3.7-* for each dependency of
FreeCAD, while all the other python3-* do not have to be touched at all).
