will assign IPv6 address space, by advertising that connectivity
through its single aggregated address allocation;"
Other regions have, or have had, similar requirements.
I'm not a native speaker, but I guess "single aggregated address
allocation" could be read to imply either 1) "one superblock [and
nothing else]", or 2) "at least one superblock that covers everything"
(with no implied statement on the more specifics).
Even if the interpretation is the second, the "benefit" of multiple
allocations is that they wouldn't need to route between all the
suballocations at least in one location in case someone is building
route filters so that it would reject more specifics.
