The eventconsumer.Consumer only supports adding sources (knots, spindles). There is no public API to remove one, and nothing in the appview or spindle ever disconnects a knot/spindle once it has been added as far as I can tell (but I have to be wrong here?).
There should be a RemoveSource function we can trigger to close the websocket connection and remove it from our event consumers.
Please let me know if I'm misunderstanding something here.
