This is dangerous, IMHO. What we do not want is developers hardcoding 2000::/3 in their implementations; we don't know what the needs of tomorrow are though. If someone invents a killer app that requires allocating a /3 to multicast or anycast, your text would have to be revised. There is indeed a difference between unassigned and treated as Global Unicast. Currently unassigned parts of the IPv6 space should not be treated as anything.
