who decides on "need"?

1. sw engineering reuseability:

would you provide a base class without a generalizable feature requiring 
every subclass implementing it? wheres the need for specialization here?

2. the linux audio developers:

"guys, theres no pcm master to access with the alsa driver on some cards 
on the mixers. everone of us must implement it now in our apps, what a 
hell work."

3. audio professionals and simple end user

"guys, i heard therere some great apps like ardour and multi-channel 
realtime audio available on linux at low cost. lets go and save much 
costs, buy this great suse and have fun. ... eh? wheres the pcm slider i 
have with windows gone? they cant even provide that? ... so the other 
apps cant be much. lets boot windows again and forget this suse..."

4. the linux kernel developers?
