Other people deploy IPv4 today, and will continue to do so, for a time frame unknown to me. So we also need IPv4 address policies.
And the time frame is the essential factor for IPv4 address policies.
If the IPv4 pool runs out, we need to handle this, policy-wise. If it doesn't, because the Internet stops growing, everybody does NAT, or everybody migrats to IPv6, we don't - but we won't know in advance, so it is useful to have a plan for the case that it does run out.
Not. As is written in RIPE NCC activity plan 2009 http://www.ripe.net/ripe/docs/ap.html To provide a fair, impartial distribution of Internet number resources guided by the RIPE community policies based on the goals of uniqueness, conservation and aggregation we must know where the goal of conservation is. When (including "never") IPv4 pool runs out strongly depends on IPv4 address policy.
we do: "distribute numbers to those people that need numbers for their work, in an open, fair, and transparent way".
Fairness includes fairness between people requesting IPv4 address today and tomorrow. Masataka Ohta
