AFAIK that's not "needed". When a request arrives to the proxy having
;gr param in the RURI, the proxy extracts the gr value, "decodes" it
somehow (not need to have such a mapping in a DB) and gets the
associated binding, so just such a binding would be retrieved form
usrloc table when calling lookup().

Note that such a feature would require implementing RFC 5628:

http://tools.ietf.org/html/rfc5628

 "Registration Event Package Extension for SIP
  Globally Routable User Agent URIs (GRUUs)"
