Whatever the solution is going to be, please remember, that the notification-daemon does not have any domain- or context-knowledge about the notification (and its contents) it receives. So any suppress-filtering will have to be based solely on the notification-type: snap-decision, ephemeral, interactive (aka clickable), confirmation (aka synchronous).
