That sort of thing does happen sometimes - either in the form of a poll or a question - in the recent test patch series there was a poll about the placement of the replay controls for example. However it's not a democratic procedure, just a way of gauging or seeing if there's a better idea out there. At times it seems more as if it's like flipping a coin and not being satisfied with the outcome so then the next resort is "ok, let's flip it for 2 out of 3".
