If you have a small cluster, without host redundancy, you are still able to configure this in Ceph to be handled correctly by adding a drive failure domain between host and OSD level. So yes you need to change more then just failure-domain=OSD, as this would be a problem. However it is absolutely the same as to having multiple OSDs per NVMe as some people do it.
