As far as I understand, when we *add* something to the stable ABI, it
should ideally be versioned. There are a couple examples of this in the
include files, e.g.:

  #if !defined(Py_LIMITED_API) || Py_LIMITED_API+0 >= 0x03030000
  /* New in 3.3 */
  PyAPI_FUNC(int) PyState_AddModule(PyObject*, struct PyModuleDef*);
  PyAPI_FUNC(int) PyState_RemoveModule(struct PyModuleDef*);
  #endif

(this is so people wanting to conform to e.g. a 3.2-compatible ABI
don't start depending on 3.3-and-upwards stuff by mistake)

However, it seems we haven't been following that rule, for the most
part.

Antoine.
