This looks suspect. Why can't you just return what Gamepad::create() returns (you may have to chance Gamepad::create()  to return a PassRef<> I guess)?

While Gamepad may be the only one using this right now, I don't think it makes sense to put this under #if ENABLE(GAMEPAD).

Right, and since we have to maintain a sparse Vector of Gamepads and we can't have null Ref<>s in that Vector, I think it makes more sense to keep Gamepad::create() returning PassRefPtr<> and play this trick here.

Sure thing.
