If you add this sort of thing at an intermediate hop, you have all of
the attendant problems of unstated or lack of consent that go along with
adding host identifiers of any kind (we largely have IETF consensus not
to work on host-identiers). If you add it only on the endpoint, consent
can be achieved in various ways. Protecting that information from
mid-point observers is an important consideration that would tend to
preclude embedding it for use by the network or transport layers.

Applications have no problems reporting to each other where they are
without recourse to lower-layer signaling.
