Huh? No, Cathedral in the sense that:
Everyone brings whatever they've got, and the anointed master architects sift through it, determine the best course of action, redirect known-bad avenues of exploration and possibly anoint new master architects from the best of the candidates.
Uh, we are talking about the same Cathedral and Bazaar thing here, right? Cathedral in the sense that only the anointed master architects get to make decisions; everyone else does what they're told and keeps their mouths shut; bazaar in the sense that everybody brings whatever they've got and hopefully the good stuff hangs around?
