Hi Michael,
Non-binding in the sense that you're not required to participate in
the registry in order to select and use ULA addresses. Registration is
advantageous and it offers COINs a simple way to resolve conflicts,
but it's not required.

Nah, just flush the registration info and put them in a hold-pool
where you don't reassign them until explicitly requested by someone or
needed to meet some other policy requirement.

Aggregation is valuable in any modestly complex network and the
back-pressure here is very mild. If you want to register a
disaggregate /48, you just create another $10 account.

Hi Owen,
I agree in principle, but recognize that no form of needs-based
allocation is likely to be acceptable for private addressing. So long
as we maintain a needs-basis for the public address pools, a uniform
policy is unlikely to be helpful for non-connected users.

No significant coordination is needed. ARIN would only manage
registration for a small subset of the ULA space. To the extent that
other RIRs want to do something similar, they need only avoid the
particular /16 that ARIN manages.

Respectfully, everything that impacts the eventual implementation of a
policy is relevant to the policy discussion, even those elements which
do not belong in the policy document itself. Also, arin-discuss is a
closed list while this is a public discussion.
