That seems at odds with the checkbox in the UI in the Tweet in this post ( https://twitter.com/apenwarr/status/1322998961704210433 ). Maybe they've changed the business logic but haven't updated the help site?

I don't know if it changed, but could have only been an improvement; if in the previous version everything would be made public.
