Question why is the IPv6-in-IPv6 header not also > used in section 5.2. The problem for the 6LBR is the same. Because the root doesn't know (unless we mandate that the E flag is propogated all the way upwards), then the root has to always use hop-by-hop IPIP for both 5.2 and 5.3, because the root can't tell which situation is in play. We (as omniscient god looking down) can distinguish the cases, but the root can not.
