Martin v. Löwis describes his thoughts [7]_ about the applicability of this
PEP to PEP 384. In summary:
* ``--with-pydebug`` would not be supported by the stable ABI because
this changes the layout of ``PyObject``, which is an exposed
structure.
* ``--with-pymalloc`` has no bearing on the issue.
* ``--with-wide-unicode`` is trickier, though Martin's inclination is
to force the stable ABI to use a ``Py_UNICODE`` that matches the
platform's ``wchar_t``.
