Some use cases:

1. swap.
2. return an auto local from a factory function.
3. desired behavior when capacity exceeds stack space (go to heap or throw an exception?).

Sometimes std::vector is going to want to transfer memory ownership. Those are the use cases I would look at first. What does std::vector<T, stack_alloc<T>> do? What does stack_vector<T> do? What do you want to happen?
