The same arguments can be made for NAT. NAT stateful translation can be
added to CPE just as easily as IPv6 support can be added to CPE.
Upgrading equipment in COs and in colos is no more difficult either.
Citing the lack of CPE support for Torrent, SIP and other protocols as a
reason to leave NAT out of IPv6 is specious. The CPE will still need
stateful translation to provide the same security, and NAT is the
simplist way to do it.
If customer support engineers are frustrated by calls for better VOIP and
Torrent support they should provide CPE that supports these protocols
securely and transparently instead of complaining about NAT.
