[arin-ppml] ARIN-prop-171 and ARIN-prop-172 - Legacy Resources

Firstly, I'll note that this thread is really more about ARIN-prop-171
than ARIN-prop-172 at this point.  The fact that we can't keep the two
issues separate on PPML is IMO a pretty good argument that we should merge
the two into a single draft policy.  Does anyone think they are really two
separate issues that need to be treated independently?  Is there any reason
we'd want to adopt a definition of legacy resources without adopting
something along the lines of 171, for example?

So here's a stab at what I think should happen:

 - 8.2 transfers should not require a change in the status of the addresses
being held, except to require that status to be contractually codified (by
the recipient signing an LRSA as a condition of updating ARIN's database).
 In particular, the LRSA doesn't make the addresses it covers subject to
utilization requirements.
 - We may be able to add some sort of grandfather clause to allow fewer
restrictions on the 8.3 transfer of legacy addresses (and a proper
definition of such addresses).  However, I don't believe that such
exceptions should themselves be transitive.  That is to say, the recipient
of an 8.3 transfer needs to sign an RSA and become subject to all of the
policies in the NRPM.
 - I could see an argument for exempting an 8.3 transfer recipient from
needs justification on the initial transfer, but IMO that exemption would
need to be time-limited, to perhaps a year, after which time the recipient
would be subject to all ARIN policies.

I think the underlying motivation here is to encourage holders of legacy
allocations who wish to transfer their space to do so in a way that keep
ARIN's database up-to-date.  In some cases, that may be an easier sell if
some restrictions are relaxed.  The supporters of ARIN-prop-171 may not
agree, but I would argue that a second goal is to encourage such transfers
to occur in such a way that the addresses being transferred are no longer
considered legacy after the transfer is complete.
