Exactly. Loose_routing mechanism is just for in-dialog requests. In fact, RFC 
3261 defines loose routing as a way for a proxy to remain in the dialog path.

Using loose route makes no sense since its purpose is handling in-dialog 
requests.
IMHO what you want to achieve is easier:
- If the proxy receives an initial request from the registrar (no To tag), 
then do loose_route (just to take off the Route header even if it returns 
false) and route the call normally. based on RURI, no more:

  if $si == "REGISTRAR_IP" {
    loose_route();  # returns false but removes the Route header.
    t_relay();  # Route based on RURI since the Route header has been removed.
  }
