The way I have always understood it - the Python that RedHat supplies is intended for it's scripts. If we install our own packages or remove any packages, then the risk destabilising the system. I have seen situations where people have removed python packages that resulted in yum no longer working, for e.g.

Hence, I have always (including from the RHEL 6.x days) provided my own local python version by compiling and packing as a custom rpm. I now use venv to do the same.
