Could you clarify what you mean by standard templates "shall not be used with incomplete types"---does this mean for instance that std::vector<incomplete_t> is undefined?

If so, is it undefined even if such a type is even only mentioned in a program without actually ever instantiating the template?
... no, but you need to be careful. Many things cause instantiation.
