I think it's possible for a precedent to be set on an individual, if not organizational, basis (i.e. the policy is kept as Official Organizational procedure but exceptions made "unoficially" on a congregational basis). Once this is done, the news will make the rounds on boards such as this and it could be the proverbial straw that broke the camel's back (though some say the 16 child abuse lawsuits settled out of court by the WT will prove to be the turning point for reform, schism, or implosion).
