So the draft
shouldn't assume a particular prefix length either. We all know that
it's usually 64 today, but that doesn't affect the argument made by
the draft.


It's always /64 for all addresses starting with binary 000, which cannot be
assigned to hosts in a real network because they are unallocated space.

We need consistency with RFC 7608 (BCP 198).


No, we don't. RFC 7608 is about forwarding, not address assignment.
