Well, I’m not sure this will do exactly what you want, but you can use the WmBrokerAdmin package’s BrokerInformation page to list the clients of type “Trigger” and then view the doc types subscribed to by each trigger.
You can drill down into the details of a document type using WmBrokerAdmin to see how many subscriptions exist for that doc type but not list them.
