You might have a point there.
I remember reading this interview by the late Dennis O'Neil a while back where he's talking about getting Frank Miller on board after COIE to do Year One. Miller was initially apprehensive about working with ''mainstream'' DC canon and not having the creative freedom he had with DKR. To which O'Neil was able to assure him that thanks to COIE, Miller had complete freedom to redefine Batman however he wanted.
I can't imagine any group editor circa 2011 being able to give the same assurance to anyone!
