I am interested in providing a package for people with root access for a
variety of distributions.

I myself have this part covered via EasyBuild, https://easybuild.io/,
which will work on any distro.  How anybody else installs a given
version Python will be left as an exercise for them (potential users of
the software are however unlikely to be using Ubuntu).

I am currently using poetry to build the package and uses a 'scripts'
section in the pyproject.toml file to produce stubs to call the main
program.  These have the shebang

  #!/usr/bin/python3

So if I can get poetry to use '/usr/bin/env' instead, then I can
probably just rely on whatever mechanism other people use to switch
between Python versions to do the right thing.
