You're lucky. In practice, you open the file a disappointed customer sends you because your software doesn't parse it. You resist yelling at whomever decided to ever do CSV support in your software because you know what it's like. But the customer is important, so then either write a one-off converter for them to a more proper CSV format, or you add - not change - several lines of code in mainline to be able to also parse customer's format. God forbid maybe also write. Repeat that a couple of times. See the mess increasing. Decide to use a so-called battle-tested CSV parser after all, only to find out it doesn't pass all tests. Weep. Especially because at the sametime you also support a binary format which is 100 times faster to read and write and has no issues whatsoever. I'm not blind for the benefits of CSV, but oh boy it would be nice if it would be, for starters, actually comma-separated.
