If putting routing entirely in end systems were a consequence of strict
application of the E2E arguments, then I would say that the E2E
arguments must be wrong or at least incomplete.  But I don't believe
that is a correct deduction.  Datagram routing cannot be done
effectively by end systems alone (you encounter problems of robustness
and scalability), so it is not really a candidate for movement up the
stack and towards the edges.
