I think that a reasonable code would allow the punished party to publicly disclose their punishment, otherwise the punishers (for lack of a better term) would do whatever they wanted. But it should be private by default.

So maybe the expected outcome is merging of HR-SJW positions and NDA-CoC so that "everyone" can feel safe

I believe that many CoC violations would include private events which the victim would like to keep private. After all, there's a good reason why we don't make all the police reports about harassment public.
