Yeah, just copy the idl into two places, instead of having a base idl.  That

copy which will slowly die.

     readonly attribute DOMString id;
     readonly attribute unsigned long index;
     readonly attribute boolean connected;
     readonly attribute unsigned long long timestamp;
     readonly attribute DOMString mapping;
     readonly attribute float[] axes;
-    readonly attribute float[] buttons;
 };
