My desktop has 32GB, and if I could I would have more. Why? Because RAM is always useful. Caching in RAM is such a nice feature, speeding up your daily work-flow. Same thing applies in the phone. IMO, the biggest RAM increase drive is graphics and UI. With 1080p screens things are getting big: textures, icons, UI elements, photos, videos, etc... And why would we artificially constrain ourselves? If the current manufacturing process makes 4GB feasible or even cost efficient, than it makes sense to use this size.
