We still have the play experience of /all/ editions, and the individual experience in the hands of the players. Modules that are nothing more than pre-made house rules for the DM to aren't exactly in the players' hands, are they?
Sure they are.
Give a cook a pantry full of ingredients, and what dish they finally prepare is in their hands. Give players a bunch of things to choose between, and the final arrangement of those pieces is? In their hands!
There is no such thing as a "house rule for the DM". It isn't like DMs work in a vacuum, and can do whatever they want, not caring what the other players* want.
*note the "other players" - the DM is taking part in play, so the DM is also a player, just in a different role. The DM is as much a player as, say, the goalie on a soccer team.
