I think what they're saying is that with some minor control over the data in your dataset, you don't need to care about escaping _in your parser_ at all. The same might be said of CSV but I would argue that in the majority of situations tabs are less semantically meaningful than commas and newlines, so it is generally fine just to strip them out.

Obviously this is not robust solution, but in cases I've seen, it works adequately. If one were to be doing it "the right way" then I agree with you wholeheartedly.

I get what you are saying, but my point is that is not CSV or TSV. It's a homemade format with its own rules that just happens to be inspired by TSV or CSV.
