So I guess there is no solution for this?
Or how about this: if I publish the topic as unlisted it will neither trigger a notification nor show up on /latest, right? So if I then “un-unlist” the topic, will it trigger notifications? It will show up on /latest, but not if I change the publication date to something further back, right?
What about summary emails, though? I suppose it can’t really be prevented from coming up there, at some point.
