Please look up this design in the alternative section of our proposal. By adding slightly redundant multi-line string literal syntax for consistency renders that complain to zero. By allowing:

SE-0168 had one focus: long literals that contain newline characters. And it does a great job addressing it.

SE-0168 does not talk about hard wrapping. Make this the only focus of your proposal. Simplify your motivation section. Strip away redundant solutions. Become expert in hard wrapping, and please give us one correct solution. Don't forget to talk about trailing/leading newlines and text editor grammars, because those were two important discussion topics for SE-0168.
