Events should be consumable by clients that would received subscribed events from the connected node. This functionality is designed to work on top of native transport with minor modifications to the protocol standard (see original proposal for further considered options). First we have to add another value for existing event types. Also, we have to extend the protocol a bit to be able to specify a sub-class and sub-type value. E.g. DIAGNOSTIC_EVENT(GossiperEvent, MAJOR_STATE_CHANGE_HANDLED). This still has to be worked out and I'd appreciate any feedback.
