So do the authority structures and procedures of play that shape and define trad play cultures.
Well those have to be defined in order to play the game, playstyle doesn't. Without an authority structure... nothing can be decided. Without procedures of play there is nothing happening. With these choices you aim for the biggest demographic and/or stick with what you have traditionally done (even better if both align) if your goal is to get as many of your past players of your various editions playing while bringing in new players as well... You also leave enough wiggle room that it's relatively easy to implement some outliers to that structure and procedures... like the player quests of 4e or skill challenges.
