I don't want to go too far down this road, as it touches sensitive network architecture issues, but I think you're thinking of this in terms of a box. Please think, instead, of a regional network with failover capabilities and widely distributed customers.The aggregate need is (at least) a

We're requesting a /10, not a /12 or /15 (devices attached to one CGN might use the whole /15). Such an allocation would be too small for a regional CGN deployment at a larger ISP, and would likely result in double-CGN. Shared CGN Space really needs to be a /10. Second, many ISPs do not control

This is not a new proposal. People have been asking for the same thing for a long time. Draft-bdgks does a good job spelling out the history (below). To say that we're trying to change the rules at the last minute is wrong. People have been asking for such an allocation considering this use
