      With the new implementation of the setFCV command (SERVER-55898) we have the guarantee that new and old DDL opeartions won't ever run concurrently on the cluster.
      So there is no need anymore to take the distributed locks on this new paths, instead we will only use the local version of the distributed lock to serialize with other DDL operation running on the same shard.
