This is not the scenario where /128 would be used for.
Right, I got the /64 and /128 problems mixed up. The above shows that a /64 is problematic. :-) But how would a /128 work?

Stateless autoconfiguration only works on /64s because it needs a 64 bit interface identifier. DHCPv6 would probably not work either, because the router and the local address need to share a subnet.
