I would say it is the common interpretation for such a sentence.

As far as I understand, if you implement a class with a C-extension,
then that class is understood to be part of Python. So if you
think there should be no way to produce a segmentation fault in
python you shouldn't allow such classes.

I do wonder what they mean with a buffer overflow. Would the following
classify:

  buf = range(10)
  buf[10] = 10

Why is it worse. You seem to think that if one has a toolbox, which
lacks a hammer, that the fact that the hammer can be abused makes
your toolbox less usefull if you add a hammer to it.

We have a toolbox, full of equipment that can be abused, yet
that something else can be abused too, seems to be a mayor
stumbling block for adding it.

No, this is good while there are still possible features that could make
python a better language
