The interface is designed in anticipation of the Usage::Static plugin, the Usage::Basic plugin doesn't require all parameters. In Usage::Static, the $haenv will necessary for logging and getting the static node stats. add_service_usage_to_node() and score_nodes_to_start_service() take the sid, service node and the former also the optional migration target (during a migration it's not clear whether the config file has already been moved or not) to be able to get the static service stats.
