There's not much choice if more IPv4 addresses aren't available. If you run out of IP addreses you need CGN regardless of whether you have IPv6 support or not, and IPv6 may decrease the load on the CGN but not remove the necessity of such.
Agreed (http://tools.ietf.org/html/rfc6264). This also seems to be why 464XLAT (http://tools.ietf.org/html/rfc6877) is attracting a lot of attention. Since consumer IPv4 is in practice a translated service today, just provide it as a translated service running over an IPv6 substrate. Brian
