No app depends on this behavior.

dsound (builtin) queriesfor these interfaces and I was showing that DMO's support the interfaces 
and at the same time trying to work out how much of the 
IMediaObjec/IMediaObjectInPlace code I could share between them

My current implementation has a complete copy of each these interfaces.

I'm happy to drop tests and just prove the interfaces exists and we can 
get back to the object original, if

that helps.
