Or am I > misunderstanding what rados_get_instance_id will return here? Yes, that's right. On smbd restart it'll reconnect and get a new instance ID. The hostname is carried in the metadata, which makes it a little easier to identify what's going on from the Ceph side. AFAICT the service record (unfortunately) remains present after rados_shutdown() until a timeout on the manager is tripped, so it's quite possible to have to registrations for the same host for a short amount of time.
