We're talking about a technology that will hopefully be used for decades. We don't want to wire assumptions about the sizes of MAC addresses during that time into the IPv6 architecture. To me it seems entirely plausible that networks consisting of large numbers of point-to-point links, assembled into trees, will be all the rage in a few years. Even Ethernet is becoming more a point-to-point technology rather than a bus technology.
