No apology necessary. So, I mostly agree with you: the value of deleting a barely-non-notable article is marginal. But as I've shown I think pretty effectively upthread, with the link to the URL pattern for AfD debates, that's not the problem that confronts Wikipedia; instead, editors on WP are dealing with a torrent of extremely non-notable articles, into which valid articles are, due most often to poor editing, occasionally getting caught up.
