Thing is, that non-technical people usually have a very hard time to grok a mixer crowded with all kinds of controls where most of them actually don't have any impact on sound at all. In PA I try to minimize the number of sliders: just one per output device. PA is clearly not for pro-audio people, so this is the absolute right thing to do. But for this I need to be able to rely on that all the mixer controls of the soundcard are initialized in a "sane" way, so that the single mixer control I have actually makes sense. > Most consumer distos do not agree with me and want the volume turned up > already by default. Yes. in an ideal world people wouldn't have to think about the volume control in there computers at all, since their speakers either come with a hw vol control anyway, are a hifi stereo with hw vol controls or are inside a laptop with hw volume controls.
