Someone on -general was asking about this, as they are listening on multiple IPs and would like to know which exact one clients were hitting. I took a quick look and we already have that information, so I grabbed some stuff from inet_server_addr and added it as part of a "%L" (for 'local interface'). Quick patch / POC attached.
Cheers, Greg
