This seems to apply to second and subsequent allocations but the
language does not clearly tie it into section 6.5.2.

And anyhow, it could be years before there is any significant volume of
requests for second allocations. Why do we need to waste time on this
problem now? For this reason, I am opposed to this policy. Whether
current policy is right or wrong is irrelevant, since the magnitude of
the wrongness is limited to a minor squeak due to the small number of
IPv6 LIR allocations.

If a few dozen LIRs come back in the next two years and ask for a second
/32 and ARIN rubberstamps the requests, it will do no harm to anyone,
even if all of those RIRs have recklessly squandered their first
