The problem with that is that the backend that I "prefer" now may not be the 
one that will be best six months down the road. And if I develop my 
application on Linux, I may not know which backend is best on MacOS or 
Windows. So I'd rather be able to say "I need a backend that can play n sound 
objects at the same time" or "a backend that can play ogg flac files".
