What about text vs. json? We might not want to add line breaks if there's a \n in the middle of a JSON payload or something, like

{
  "key": "my super long value\nwith a new line in it"
}

[Alex-Tideman]

That's kinda the whole point, when it's json with several fields, and users want to line break long strings in a json payload. Like that second pair of screenshots, I think it's always easier to read with a linebreak.
