Seriously I think that this topic perfectly fits the description that you can please some of the people some of the time.
Never having been to one yet and looking from the outside in it is my observation that so far the current scheme is workin pretty darn good.
I say keep things flexible with as little HARD RULES as possible and see no reason to not continue both cenerios simoltaniously.
