again, don't discuss it here. do it in ipngwg, otherwise spec writers
do not get any comment from you.

yup. i agree with your point.

basically, the current draft relies upon the existence of multicast
reachability to all the routers, and the group management of the
multicast address would automatically let you reach all the routers.
router renumbering protocol itself does not try to make a list of
