My gut feeling is that given that we don't override yaml conversion at
all, we shouldn't attempt to address this behaviour. Either we should
add a nice method ala to_xml and to_json that accept :only and :except
and friends, or we should leave this for the user to deal with. The
only place where I'm using .to_yaml in an application is with my own
implementation, and perhaps people are relying on the current
behaviour to include associations? Seems unlikely but... who knows.
