Actually, you _do_ make the application's job easier because it
doesn't need to keep state.
What are these "certain possibilities" that you are talking about?
As long as it is possible for an app to figure out what a meaningful
volume step is, I don't see what keeping state in the kernel could
prevent you from doing. It currently _is_ possible to figure out
the hardware step: mixerctl -w outputs.master++ works. I don't think
anyone is proposing removing that feature.
Things that I can think an app would want to do with volume:
set volume to level X
increase/decrease the volume by one step
increase/decrease the volumn by one meaningful step
All of these are possible with a stateful volume control.
What else can you do with a volume knob?
