Yes but since API states that returned type is an Icon it should be done anyways - because we might wrap up Icon in ImageIcon locally but we can't force any 3rd party Java implementation to do the same so there will be requirement to check the returned type - unless we change the API to always return ImageIcon or MultiResolutionImageIcon or something even more complicated.
