FWIW, this issue arrived from pygresql, see TestSuite2 in

Here, the objective is to wrap a number of test suite classes
with a single setup/teardown, covering all test cases that occur
in either test suite, so that the expensive database creation
happens only once. I can't see how either class or module level
setup could easily replace this.

That sounds good to me.

You mean, for test suites that have been modified to explicitly
support Python 2.7?

I think this would then be for python-dev to discuss.
