 This philosophy is similar to that which we have for containers:  It would be super easy to create `vector<T>::push_front(const T&)`.  But that would make it too easy for programmers to write inefficient code.  The compiler helps remind the programmer that perhaps `deque<T>` or `list<T>` would be a better choice when he attempts to code with `vector<T>::push_front(const T&)`.
