Mandatory fields for group site setting

In the commit https://github.com/discourse/discourse/commit/98fc6141620a2001bf2414716c300fbed23d88a3, the admins and moderators groups were added as mandatory to some settings. In addition to the effect that this avoids permission conflicts, it also highlights that staff can always do those things and you cannot change it.
However, there are other settings where the description mentions “Staff users can always…”, but the admins and moderators groups were not added. For example hidden post visible groups and chat allowed groups.
Maybe there are even more settings where this could be added, because staff is allowed anyway, like for example delete all posts and topics allowed groups, edit all topic groups and edit all post groups.
Is there a reason why the admins and moderators groups were not added to these settings as well?
