> I'm only aware of PyQt which uses the stable ABI. Is there other projects using it? Do these projects check for Py_TPFLAGS_HAVE_VERSION_TAG or Py_TPFLAGS_HAVE_FINALIZE flag? I think there are. Who knows how many; they're not required to register anywhere. If the flags do end up being removed, it would be nice to reserve the bits (in a comment), so they aren't reused too soon. Also, ISTM that PEP 387 applies, and requires warning for two releases. How can that be done for flags?
