In reviewing this draft, I was most concerned that this mechanism could be used by an attacker to push traffic towards or away from a node.  If the messages are authenticated then I tend to agree with your assessment that this draft doesn't introduce any new security considerations beyond those in [RFC2328]/[RFC5340].  If not, well all bets are off.

I did note a couple of editorial nits, but I sent those directly to the authors.
