I disagree, I’ll come back to this in a moment 
Granted, that may well be the case and we will probably do as you suggest or simply post our drafts in the Staff category and go from there 
So coming back to the issue of this being a bug or not…
I don’t quite understand how the issue of Unlisted topics become listed via references was seen as a bug and the issue we have here of Unlisted topics being leaked by notification to some users, is any different?
The concern is the same, unlisted topics are announcing / revealing themselves in certain situations.
