  connection tracking is useful for:
             - stateful packet inspection       
             - IPsec
             - queuing/scheduling decisions

  The ability to make a decision for a microflow once and then remember it
efficiently for that microflow is very useful. NAT/NAPT is just one situation
where it is required.
  One hopes that IPv6 NAT will never be needed.
