I suppose he wanted to say that since Discussions is a "separate" area of the wiki and doesn't show up in RC, it doesn't disrupt the "content life" of a wiki and the editors who mainly dedicate to that. I also agree with that, although I still think everything should show up in RC (after that, it's up to someone to filter what he likes to see).
