I suggest you go ask them yourself at #fpc on irc.freenode.net.
From what I cought and seen it would seem they got their worked chopped up to specific parts of which one or more people are "chiefs".
Mostly these are the core developers(holy eight ).
I don't think there's a single boss. They just agree on the mailing lists mostly and it goes in.

But i'm a mere user so don't listen to my rant here and go see yourself ;-)
