Agreed. In particular, "no worse than TCP" is a bit of a low bar. We need to be robust against packet injection attacks.

As for IoT, did we not have a couple of IoT talks during the last IAB plenary? Most of what I read on this thread was presented here: http://www.ietf.org/proceedings/92/slides/slides-92-iab-techplenary-2.pdf. The discussion should probably move to an IoT specific list.
