Yup. A big benefit of using test_when_finished is that the knowledge of what cruft needs to be cleaned is isolated to the exact test piece that would create the cruft. Instead of test_when_finished, We could use the other convention to clear what others may have left behind to give yourself a clean slate, but that requires you to be aware of what other tests that came before you did, which will change over time and will add to the maintenance burden. And to some degree, the same downside is shared by the approach to use test_atexit.
