And during those 11 years. Nobody implemented this rule specific to ::/3.
I can implement it today in some of our code if you like :-). But it seems
unlikely to make a difference, since the rule only applies to unicast
addresses in ::/3, and no such addresses have been released to the RIRs.
That in turn is unlikely to change until we run out of 2000::/3, and even
then we'll likely move on to allocating addresses out of 4000::/3 instead
of from ::/3.
