pg_basebackup does the equivalent of pg_start_backup and pg_stop_backup for
you. It is not helpful, and might even sometimes be harmful, to do them
yourself when using pg_basebackup.

That certainly isn't my experience. If you find sites that don't mention
-x, -X, or --xlog-method, then I would be reluctant to take any of that
site's other advice seriously.

But note that in version 10, -x will go away and the default will be
changed so that not specifying anything will be the same as -X stream.
perhaps you are reading advice aimed at a future version.
