In your previous mail you wrote: The enhance privacy that you consider *a rare benefit from the CGN* it is actually a BIG issue for a Service Provider, because we are quite often requested by the authorities to be able to track who was the user who did something and the only information that we have is the source IP address. => with only the source IP address there is nothing you can do so your argument is not about the problem analyzed in Mohammed's I-D, but for authorities who need to understand what is a CGN (or to make CGNs illegal... :-).
Being able to identify the users behind NAT, for example by using the HOST_ID proposed in this draft, is in my opinion an important problem to be solved no only for content providers but also for Service Providers. => the HOST_ID doesn't solve anything if the authorities provide only the source IP address in their identification requests, and if they provide more they can provide the source port...
