I don't think that specific IANA-delegated prefixes belong in this document.
And a few weeks ago I suggested limiting the /64 rule to currently delegated
address space, and was loudly told "No!". What we need to get across
is the notion that this is a parameter, not a constant, and today's
setting of the parameter is 64. I strongly suspect that the document editor
has got that message and will come up with some new text.
