Not heated seats specifically, but any "option" that was cheaper to include than not. That's the definition of a standard feature, where it's just built into every car.

Power windows were originally an expensive option, but they got cheaper, and the fraction of cars ordered with manual crank windows dwindled, to that point that power windows are simply standard on most cars now.

If somebody said, okay every car has power windows but yours don't work unless you pay a monthly fee, I'd break out the wire cutters right in the dealer lot and fix the problem myself. Screw that. It's a standard feature and someone broke it, I'm fixing it.
