If I understand the rules as written correctly, the more people in Conjecture know a Secret, the harder it is to change it to Private-to-Conjecture. This seems more like a minor bug than a weird quirk, IMO, and I’d personally prefer a scheme that scaled in less than perfect proportion with group size, both to respect the dynamics of Secrets in large groups better, and to dilute the decision this would currently give to small groups.
