My washing machine has a wheel to select multiple, heat-specific programs but also has a "cold" switch for other programs. I seldom use the heat specific ones, unless I'm particularly interested in a hot wash.
So I guess that the mileage may vary by country (I'm in Spain) and how old a washing machine is (mine is quite old).
While PDX-published games may suffer from the decouplement of features between DLCs, at the very least PDS-developed games have a built-up expertise when it comes to managing this.
As for MMO model, it's a hard sell because purchased things get made "free" for new comers. It's one of the crux that EU4 faced when they rolled many DLC features into the base game.
