Right, but if you're picking CSV, you likely expect to interoperate with a provider that's not yourself. And then there's no way a parser can handle all CSV formats in the wild.

e.g. the example from my comment on the last CSV discussion (https://news.ycombinator.com/item?id=28223719)

What variant is this:

    1,5,Here is a string "" that does stuff,2021-1-1

What is the value of the third column?

Is this a CSV file without quoting? Then it's

    Here is a string "" that does stuff

Or is it a CSV file with double quote escaping? Then it's

    Here is a string " that does stuff
