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?
