Oh right, Cython seems to be a false positive.
A code search found 3 references to __Pyx_PyObject_LookupSpecial():
PYPI-2022-01-26-TOP-5000/Cython-0.29.26.tar.gz:
Cython-0.29.26/Cython/Compiler/ExprNodes.py: lookup_func_name =
'__Pyx_PyObject_LookupSpecial'
PYPI-2022-01-26-TOP-5000/Cython-0.29.26.tar.gz:
Cython-0.29.26/Cython/Compiler/Nodes.py: code.putln("%s =
__Pyx_PyObject_LookupSpecial(%s, %s); %s" % (
PYPI-2022-01-26-TOP-5000/Cython-0.29.26.tar.gz:

PyObject* __Pyx_PyObject_LookupSpecial(PyObject* obj, PyObject*
attr_name) {
Oh, that's not "_PyObject_LookupSpecial()", it doesn't use the
_Py_Identifier type:
static CYTHON_INLINE PyObject*
__Pyx_PyObject_LookupSpecial(PyObject* obj, PyObject* attr_name)
{ ... }
