It's not that it is unsafe today when it was considered safe yesterday. It's just that now years later it looks unsafe in the new eyes of the regulator even though no associated faults have been demonstrated in its limited service life.
Obviously there are many previously certified products out there from all manufacturers that may fit this interpretation, so the issue needs adjudication in fairness. IMO the issue should be treated under continued airworthiness of a certified product where the good experience trumps the what-ifs.
at this time I'm not predicting the outcome but I am disappointed in the suggestions of previous posters that nobody is to be trusted
