      Description

      In MongoDB 3.6, the feature compatibility version (FCV) flag is used to signal whether operations should use UUIDs or namespaces. If the FCV is seen to change in the oplog when synchronizing, the program should abort with an error.

      A reasonable heuristic is that any operation that modifies admin.system.version should error, but we should confirm with the replication team.
