Thing is that if somebody wants to use the Phonon utility classes on embedded 
and he has to use a second library then that's more expensive than having the 
same classes in only one lib, no?

And adding features in a later release of the firmware is still compatible.

I'd imagine the developer to start out with as many features disabled as 
possible and only enable a feature when needed.
