I agree; no doubt, deploying IPv6 is urgent. But, unfortunately, operators often face multiple urgent issues at the same time. In any case, the urgency that I referred to is a reflection of advice from various ARIN leaders. Obviously, there is a future date at which ARIN will be unable to donate the /10 prefix because of IPv4 inventory exhaustion. More near-term is the prospect that operators will deploy CGN using global unicast addresses. This might have negative repercussions for the operator and/or their users, along the lines of scope detection etc. It definitely has negative repercussions for the rate at which RIR inventories are exhausted. In other words, the sooner we act, the more benefit this reservation will have. That doesn't imply that we have so little time we are unable to address the issues raised by the IESG. But we certainly don't have the sort of time that many drafts commonly require, per the stats at http://www.arkko.com/tools/lifecyclestats.html for example.
