I'm not sure about this, but if someone in a private room subscribes to the room's atom feed on a public aggregator like Google Reader, Bloglines, MyYahoo! etc. isn't the contents of the private feed going to become public? By removing the autodiscovery code for the feed, you make it harder for people to inadvertently compromise content that other room members posted with the understanding that it would be private. Personally, I think there needs to be a clearer definition of what private means on FriendFeed.
