It's not our job to test Python features, especially not version-dependent
features.

You have not explained why we need to change anything.  The current
approach may be a bit of a kluge, but it works fine for our purposes,
AFAICS.  Also, I would bet that those tools would not know anything
about converting PL language names between 'plpythonu' and 'plpython2u'
and 'plpython3u'; so even if we used one of them, we would still need a
layer pretty similar to what we have.
