Review comment:
Yes, in some cases.
For a purely local setup, or a cluster setup where submissions are submitted
internally (like, a master node running the JM + client), no change should be
required.
It is only necessary if submissions are to be accepted from the outside. In
that case I would think it is also good to require both to be explicitly
configured, because only the REST API should be accessible from the outside.
