to deal with some broken NAT/STUN devices, when you are sure there is a single phone, but each registration gets with a new port for each register refresh.
How usefull is this? How do you get packets from the outside through the NAT if the NAT is losing its mappings
the nat might not lose the mappings. Let me give an example where i encountered a real need for this. Some time ago mobile phones starting introducing sip phone applications to connect via wifi. It happened many time that they crash and upon reboot they asked a new stun and got new binding port, while the old contact was still valid. If registration time is long enough could happen to have several contacts in location table but only one valid. kamailio/openser was forking, of course the right branch was answered, still, extra resources were used.
