As a user of Phabricator in a data-sensitive industry we are trying to limit access to projects in a very strict manner. It would be great to be able to limit the ability add/remove users to a specific person, i.e. the Project admin.
Would it be (is it already) possible to create a Project administrator role? In this role, the Project administrator would:
* be the only person able to add/remove users
* not be permitted to leave the project
