Sorry for the confusion. The exclusion clause in the PEP should probably be replaced by an explicit list of macros which are made available. It not necessarily obvious that a macro only uses features made available through the ABI without actually digging through the headers. In the case of Py_INCREF()/Py_DECREF() the macros do use private macros which the ABI omits.
