I KNOW that, but I thought this effort is a continuation of the
modernise-and-make-it-maintainable effort started at 1/6.

OK.  So A, B and super (and super/sub) are the ones that survive
throughout the test, and individual test (including the "let's try
cloning the super into super-clone" at the end of existing tests)
would follow create-use-remove pattern?  Perhaps that can be left
as a comment before the last existing test, e.g. "A, B and super are
permanent, and from here on, if you create a clone of them for
testing, remove your clone once you are done", to inform the test
writers of this convention.

Thanks.
