This could be an option, but it is still half-broken - or at least
implementing it is not trivial - as spinx-pre-install is the
script which recommends what packages are needed on openSUSE Leap.
and on RHEL8 (and based) distros.

Internally, it needs to run sphinx-build --version to check if
Sphinx version is compatible with the build. So, adding support
for a PYTHON env is still half-broken after this series.
