Why does dynamic router continually and automatically re-route the same message unless "null" is returned from the dynamic routing method? The EIP certainly does not specify this as the behavior for a dynamic router. The only connection from the potential recipients back into the router is by the control channel, which is the mechanism for the potential recipients to register the rules by which messages will be routed to them. The Dynamic Router EIP specification does not indicate that the control channel is a mechanism by which the message should be routed back to the router.
