I guess that can work. In this case I would install with pip install --user and move the
files out of .local into an appropriate place in /opt/<app>.

At work I package a lot of packages for python and what we do is get the sources, 
review them then turn them into an RPM using the setup.py to do the file placement.

We do not use the wheels from PyPI ever. They may not match the claimed sources.
Which I have seen a few times; the version on PyPI can contain helpful patches that
are not in the sources.
