Actually I was thinking about this in simpler terms and just expected
the client to support password change using the secure connection that
was established using the old password.

I think the fact that users use password schemes is one of the main
points of the entire discussion. If server and client were simply to use
a hash of the password as shared secret this could be solved, right?
