The actual backend of CPython requires garbage-collected container
types to implement tp_inquiry and tp_clear methods, but user-defined
types apparently aren't required to conform.
tp_inquiry doesn't exist, you probably mean tp_traverse. tp_traverse
is completely irrelevant for python-defined

What is your basis for this claim, if it's not the mere unreliability
of finalization? IOW, are you not merely begging the question?
