It's not easier or simpler since you need the exact same checks and steps, just with a different delimiter. It doesn't matter if you need to do them less times for certain inputs since you need the same checks, the same encoding/decoding steps and so on.

Do you think you would have an easier time writing a TSV parser than a CSV one? If so, why?

And wrapping in quotes does not solve anything since now you need to both check for escaped quotes and tabs/commas. It's the same but one level deeper.
