While in general I agree to your suggestion, Matthias' point rather
seems like a non-argument to me.
I agree that one should consider possible negative implications of wrong
usage of the feature in question. But I don't agree that the risk
created by "documented existance of such a feature" is an argument
against implementing it. Same logic applied again, we should stop
shipping crypto software in distributions at all just because in some
countries it might bring you into trouble, right?
