I believe what with the current builds the camera slider shows up without having to double press the home key. So with currently released iOS, it is double press home, tap the camera icon. In current leaked builds, it is single press the home (or sleep) button and slide the camera icon. same number of steps. I think the found many people were not aware of the double press feature so they decided to make it always visible. But they had to make the trigger a gesture instead of a tap, since being there all the time would lead to accidental taps and launching of camera.
