Thanks for those coments, which I cut, because I think they can now be turned to text. You asked a question about one comment, see below:

GF:
Could the WG consider to also add the first two sentences to the security considerations?
Bob:
Sorry, which two sentences?

These were the two sentences, the rest of the para explained what PMTUD was, and probably could be left to the reader:

   "Packetization Layer Path MTU Discovery (PLPMTUD) [RFC4821] does not
   rely upon network support for ICMP messages and is therefore
   considered more robust than standard PMTUD.  It is not susceptible to
   "black holing" of ICMP message."
