Getting the right number of steps is really hard. Even with a receiver with a volume knob denominated in decibels-- there's 30 useful steps between really quiet and really loud for content that is using the full volume of the track. Content that is quiet, or quiet in places, can easily need another 15 steps. And sometimes, sitting in the room with the atten set to -34 dB and -32dB feels really different. So that says you need 22+ steps to be sufficiently expressive, but everyone wants a 1-10 scale.
