DISCUSS:
----------------------------------------------------------------------

An easy item to address. Per Section 5, “Specifically, TE traffic may be
delivered to the wrong tail-end router, which could lead to suboptimal routing
or even traffic loops”, the impact could also include providing access to an
attacker. Perhaps:

OLD:
Specifically, TE traffic may be delivered to the wrong tail-end router, which
could lead to suboptimal routing or even traffic loops.

NEW:
Specifically, TE traffic may be delivered to the wrong tail-end router, which
could lead to suboptimal routing; traffic loops; or expose the traffic to
attacker inspection or modification.
