I think PG did comment on a subsequent post asking why post on subject[0] was taken down. I am not sure if commenting on a soon-to-be-killed post constitutes an official comment though, perhaps it was decided there is no need since according to policy meta-concerns should be dealt with using email.
So instead of having a thread pop up to address meta-concerns, they have to be dealt with privately causing any front page title change to now have 10-20 comments at the top discussing the title change. All the actual discussion about the article is well beneath the fold now
