::::there is a difference between marking the articles, and notifying the editors. Marking the articles confuses the ordinary readers of the articles; notifying the editors, does not. And I, like most people with  long watchlists, do not watchlist every article I edit.  And , like most people with long watchlists, my watchlist is set to hide bot edits, so I would never see the addition of the notices unless I edited the article again in the period of a week that the notice was there. But I certainly notice everything posted to my talk page, and most active people are active at least once a week. The basic need for is a way to move significant discussions at TfD and the other "minor" XfDs into wider notice. The need for this DRV, just as you said, is to realise that even among the people who participated, there was not sufficient consensus to delete.''''''
