The stated problem is a result from some implementors' decisions
to implement strings inefficiently.  Same problem would occur if
a naive implementation uses linked lists to implement vectors for
example.  Yet the existence of a naive implementation of vectors
does not by itself warrant a change in the vectors API, right?

What's the real problem that this proposal attempts to solve?
