I think you will find that you will have to add it back later because 
both interfaces are commonly used.

The private interface is used for enumerating devices and is the only 
way of getting some information about the actual hardware.

The buffer interface is commonly used to determine special hardware 
effects.  Programs do check even if wine doesn't implement them because 
most windows sound cards don't either.  In fact, now that you will be 
using openal you might have the opportunity to actually add real effects!
