What makes you think that if people manage to misimplement CSV parsers and generators they are not going to misimplement other formats? At least with CSV it’s always easy to implement some sort of heuristic that splits the rows correctly.

The only times when I had to deal with the issues you describe I was supplied with the data from a literally dying company. They just didn’t give a damn. Changing the file formats wouldn’t change anything - they would still find a way to mess it up.
