And that's what we are going to end up with ultimately.  But I don't see
that a clean cut from Python2 to Python3 in a single step is easily
feasible and testable for all targets at once including all GUB targets.

If we are talking about "just a handful of shims", that certainly sounds
like causing the least trouble.  The plan would not be to maintain them
for extended amounts of time but rather to help getting the Python3
transition over with with the least amount of pain.
