@Casey Bodley commented:

• Currently admin ops API does not have the ability to delete zones/zonegroups,
  maybe the orchestrator should do it?

• Before deleting initial default configuration, the realm has to be configured,
  because rgw daemon has to run on a zone, being the initial default one or the realm default one.

In addition to deleting the "default" zone and zonegroup, we should also delete the pools associated with that default zone. The dashboard should make it very clear before starting that existing data will be deleted and is not recoverable.
