We could have a method returning a separate interface I suppose:

     partial interface MediaStreamTrack {
         Constrainable getConstrainable();
     };

Or if all you're looking for is a specification editorial aide, then 
maybe this:

     interface MediaStreamTrack : Constrainable { ...
     };

     partial interface MediaRecorder {
         // NOTE: Constrainable interface goes here
     };

     interface Constrainable { ...
     };

Unfortunately, MediaRecorder already inherits from EventTarget and 
webidl doesn't allow multiple inheritance, so that one gets a little ugly.
