This makes it so scripts with complex fields will still output all
fields to output csv/json files, while only showing a user-friendly
subset unless -f/--field is explicitly provided.
While internal fields are often too much information to show by default,
csv/json files are expected to go to other scripts, not humans. So more
information is more useful up until you actually hit a performance
bottleneck.
And if you _do_ somehow manage to hit a performance bottleneck, you can
always limit the output with explicit -f/--field flags.
