      Description

      The validation added in SERVER-32105 breaks Queryable Backup of 3.6.1 sharded clusters:

      InvalidOptions: Cannot start a shardsvr as a standalone server. Please start this node as a replica set using --replSet or the config file option replication.replSetName
      

      Unfortunately the queryable mongods are readonly and there's no way to initialize the rsConfig for them. Can we relax the validation and add an exception to queryable backup mode?
