Comment (by karsten):

 Hmm, I'm not a fan of throwing "not available" runtime exceptions.  That
 feels a lot like bad design, which we can, in theory, fix with the move to
 2.0.0.  But if we don't, any objections if we just document this in the
 overridden method and just return the default `null` or empty something?
