Our application is using change stream events to publish changes as kafka events for our customers. Sometimes we are in need to decide if an event should be send by kafka or not. Right at the moment the only way would be to decide based on additional fields on our document.

It would be nice if there is an opportunity to include query comments to change stream events or some kind of meta data to get some info about the origin of the operation. This would be useful, to decide without any need to add additional fields to our data model.
