By miracle, would the JSON output mode recognize JSON[B] values, and avoid the escaping?

I agree there should be a copy option for “not formatted” so if you dump a single column result in that format you get the raw unescaped contents of the column. As soon as you ask for a format your json is now embedded so it is a value within another format and any structural aspects of the wrapper present in the json text representation need to be escaped.
