It's not that they aren't supposed to be published or talked about, its that the caffeine thing was never an "edict" in the first place. The edict was no coffee or tea, and culturally that became "no caffeine" because that was a common link between the two. It became a common enough belief among lay-members over the case of many decades that the church in recent years put out a statement clarifying that caffeine is not in fact prohibited or addressed in any way by church doctrine.
