docs: Tests if this user can change the hierarchy.
  
          A return of true does not guarantee successful authorization. A
          return of false indicates that it is known performing any update
          will result in a PermissionDenied. This is intended as a hint to
          an application that may opt not to offer these operations to an
          unauthorized user.
  
          return: (boolean) - false if changing this hierarchy is not
                  authorized, true otherwise
          compliance: mandatory - This method must be implemented.
