I am kind of amazed how people nag about having to parse practically a random file.
Having header or not should be specified up front and one should not parse some unknown file because that will always end up with failure.
If you have your own serialization and your own parsing working yeah this will simply work.
But then not pushing back to the user some errors and trying to deal with everything is going to be frustrating because amount of edge cases is almost infinite.
Handling random data is hard, saying it is a CSV and trying to support everything that comes with it is hard.
