I agree. And some tools support it, e.g. Miller.[1] There are a lot of power tools for CSV. All they need to do to support this format is to support it as input and output. It should be possible for example to add support to Csvkit[2] as input/output ("format"). Just based on HN comments alone (these things always come up) there is a decent demand for this kind of format. And there are a few implementations out there. But the implementations often look more like standards or proofs of concepts rather than full-fledged implementations. (A full-fledged implementation should probably provide functions/programs to convert to and from CSV as described in RFC-4180.) We could make this happen.
