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...
