> For compatibility with extensions built with older Pythons you should define new type flag and read tp_fastcall only if the flag is set.

Can you comment on https://github.com/python/cpython/pull/4944 why you think that such compatibility should be guaranteed? According to PEP 384, the layout of PyTypeObject is not part of the stable ABI.
