Owners also see the plan property associated with a namespace: 

[
  {
    "id": 1,
    "name": "user1",
    "plan": "silver",
    ...
  }
]

Users on GitLab.com also see max_seats_used, seats_in_use and max_seats_used_changed_at parameters. max_seats_used is the highest number of users the group had. seats_in_use is the number of license seats currently being used. max_seats_used_changed_at shows the date when the max_seats_used value changed. All the values are updated once a day.

max_seats_used and seats_in_use are non-zero only for namespaces on paid plans. 

[
  {
    "id": 1,
    "name": "user1",
    "billable_members_count": 2,
    "max_seats_used": 3,
    "max_seats_used_changed_at":"2023-02-13T12:00:02.000Z",
