It is not about security. It is about finding enough bits to service 7 digits number of subs.
IPv6 takes care of that problem quite effectively :)If there is a major amount of gear in the network that will not support IPv6 (apply bat to vendor as appropriate), then I can understand going down the road of IPv4 + CGN, but I would consider that to be an absolute last resort. Not much upside, lots of downside.
