hasattr() can return True, False, or raise an exception. But PyObject_HasAttr() just returns an integer: 0 for False, not 0 for True. There is no way to return an error, and existing code doesn't expect that PyObject_HasAttr() returns an error. Leaking an exception from PyObject_HasAttr() will break existing code.
