If we merge #8001 before this one, we can completely get rid of the old test here.

Some benchmarks:

• main:

  $ pytest test/test_transforms_v2.py::TestSmoke::test_common test/test_transforms_v2_refactored.py
  [...]
  === 7928 passed, 34 skipped, 96 warnings in 19.48s ===

• PR:

  $ pytest test/test_transforms_v2_refactored.py
  ========= 6260 passed, 34 skipped in 16.01s ==========

Although we now test multiple configurations per transform, we ultimately end up (insignificantly on our scales) faster than before, because we removed some duplication between the legacy and current tests as well as doing some refactoring that was not possible in the legacy tests.
