> We could ignore all functions that start with _Py.

Some symbols starting with _Py are indirectly part of the ABI. Example of Include/cpython/pyctype.h:

#define Py_ISLOWER(c)  (_Py_ctype_table[Py_CHARMASK(c)] & PY_CTF_LOWER)
PyAPI_DATA(const unsigned int) _Py_ctype_table[256];

Even if "_Py_ctype_table" is not directly part of the C API, it's technically part of the ABI.

If tomorrow, _Py_ctype_table is truncated to 128 items, it would be an incompatible ABI change.
