  If we operated at L3 we could just start processing packets in the new Ztunnel.
* We do not operate at L7, so we cannot signal to the application, in any way, that it should reconnect (to the new Ztunnel).

Realistically, that means the best we can do is:
* Ensure that, at any point in time, any _new_ connections will succeed. There is no period where new connections are dropped.
