There’s a bit more to it than just their visual organization. In Discord, a user only needs to join a single community to access all of that community’s rooms (they don’t have to manually join each one to have it in their feed).
The admins of that community can then seamlessly create or delete rooms within that community (which is seamless for every joined user), and can independently adjust what the base requirements are to view, enter, or interact with each room, and then give an individual granular permissions of what rooms are visible within that community.
