Same goes for sub-team name? I.e. don't put private project names, future release date related things etc in there?

"The very existence of subteams are hidden from all who aren't members of the subteam. Thus, if you wanted to create the team `lets_fire_bob.just_kidding_fire_bruce`, then Bruce would have no way of knowing his number is up."
