Jouni, At this point, it appears that just adding one IID range reservation to those of RFC5453 (to be registered by IANA), can do the job. No need to change any existing RFC.
Besides, as suggested by Brian, a different IID range than that of the current 4rd draft can be recommended by 6man. In absence of new fact, this can be IMHO a way to close this subject in 6man.
