You can choose a client that only indicates that an author wants to retract a post, and they can also provide a reason for the deletion. This is not about owning up to posts or mistakes, but about fixing typos, removing tracking params in links, and stuff like that. Since, as you say, you cannot actually delete a post that has been published and synced outside of your control, the fear about people hiding things is unwarranted really.
