I have not objections to backporting tests and test infrastructure. Testing
is good and I don't see how tests are going to introduce regressions.

The whole idea behind the backport policy is to keep the chance of a
regression at a minimum, get users fixes they need, and keep maintenance
work down so we can have some time for some development. It sounds like
backporting the infrastructure might help with future backports, reducing
the maintenance work so that in it self fits into those goals.
