IMHO, the "universality" of 64 bit IIDs went down the drain the moment router vendors allowed longer than 64 bit netmasks to be configured. For the routers I am most familiar with (Juniper, Cisco), longer than 64 bit netmasks have been configurable for many years. And such masks are heavily used for provider backbone links. The IPv6 standards community can of course continue to pretend a belief in universal 64 bit IIDs - thus ensuring that they are out of touch with IPv6 reality...
