I did all my testing on debian sid which has rather complex and
detailed controls with pulseaudio.  But Raspbian has a custom simple
mixer and I'm concerned about breaking that.  I didn't want to name
names.

I know of other operating systems designed specifically for the RPI for
multimedia that I don't use, so I'm a bit concerned about breaking
those as well.

Honestly, it would be cool to have just the HDMI and Headphone virtual
devices, but I'm not sure I'm confident enough in my testing yet to
drop the traditional device yet.
