I'm glad to see documentation of design decisions (& changes thereto). I wish there was more of this, so there could be less "What were they thinking in 2005 when they removed the on-link assumption!?" in 2010 ;-)

I found Section 3.3 very hard to parse. This section, in particular: The second option might succeed in reaching a destination (assuming that one is reachable) but is more complex to implement, and isn't guaranteed to pick the correct destination. For example, there is still ambiguity about which link to use if more than one node answers the solicitations on multiple links. In previous parts of Section 3, we seemed to be dealing with a host attempting to send a packet using a known AAAA record. In this section, it's not clear whether the argument is that a host with multiple interfaces has an interface selection problem that is unresolvable because of on-link assumptions, or that the on-link assumption again causes a poor ordering of attempts to reach a host, or causes ambiguity because of non-globally unique addressing. Some clarification would probably help here.
