I'm not sure I even buy that.  JSON data in particular is typically
multi-line, so how will you know where the row boundaries are?
That is, is a newline a row separator or part of the data?

You can debate the intelligence of any particular quoting/escaping
scheme, but imagining that you can get away without having one at
all will just create its own problems.
