Can you confirm me these 2 points?
i) In fact, the "host" parameter is needed only if in ceph.conf there are
multiple [client.radosgw.{instance-name}] sections for different radosgw
servers. If there are only the sections [client.radosgw.{instance-name}]
which concern the current radosgw server, the "host" parameter is useless.
In fact, everything happens as if the default value of the "host" parameter
in the [client.radosgw.{instance-name}] was $(hostname).
ii) The {instance-name} in [client.radosgw.{instance-name}] must be necessarily
unique _in_ the cluster, _not_ unique by radosgw server.
Is it correct?

I'm still interested by this question.
I know it's possible to use the same keyring (ie the same ceph account) in
multiple radosgw servers but I don't know if it's recommended or not.
Thanks in advance.
