Here’s a feature request to allow group owner to not be member of the group, as discussed in Group owners for managing group membership. Let me know if there’s more clarification required here. Thanks, @sam!
The reason why I really like the concept of this feature is that, for many sites, that are two workflows:
(1) the worfklow of administering the site membership processes
(2) the workflow of administering what the site is here for. For us, it is delivering meals.
It makes sense for staff to be responsible for (1). But (2) should be administrable with a different cadre. This feature essentially enables the site admins to create a hierarchy of connected roles that are focused on the workflow of whatever the mission of the site is.
