Behavioral/statistical telemetry is very important for security, traffic engineering/capacity planning, and troubleshooting purposes. The overwhelming need for it is orthogonal to any schemes for hashing NAT source/dest ports.
What's needed in this regard for CGNs (for any NATs/proxies, really) is something analogous to Cisco's NSEL for ASA, hopefully implemented as IPFIX EEs.
