Great job! I've added a link to that to the PEP.

There are two improvements you could make:
- Some of the functions in the first list return Py_ssize_t; calling
   them can cause truncation if the result value is larger than INT_MAX
   (and it is assigned to an int). To find those functions, do
   grep 'PyAPI_FUNC(Py_ssize_t)' Include/*.h
- Usage of the "old" function pointer type name (e.g. intobjargproc)
   likely also indicates an error, since many of these pointers have
   changed there types. I believe the only exception for this is inquiry,
   which still has legit uses, in nb_nonzero, tp_clear, and tp_is_gc.
