This option allows restricting the shown fields in the output modes that would normally show all fields. It allows clients that are only interested in a subset of the fields to access those more efficiently. Also, it makes the resulting size of the output more predictable. It has no effect on the various `short` output modes, because those already only show a subset of the fields.
