"A bit laborious"? That seems enormously out of proportion to the
benefit of putting this test case into back branches. It will have
costs for end users too, not only us. As an example, it would
unecessarily block some upgrade paths, if the upgraded-to installation
is slightly older and lacks the necessary --1.X.1--1.12 script.

I do not think this should happen at all, whether you're willing to
do the work or not.
