I'm guessing it's a bug. 

Though it's also unnecessary... The Peer interface always exists, so there's 
no value in listing it. The Introspectable and Properties interfaces are only 
useful if you're going to call it and you'd get the same values as you're 
otherwise getting with GetManagedObjects.

The one that matches the return value from GetManagedObjects.
