In practice, I made heavy use of this format at my last company. I was dealing with lots and lots of Google Sheets where I knew there wouldn't be any tabs or returns in the columns, and my code was all ad-hoc stuff that would never see production, so I'd just read in files, line-by-line, split on "\t", and bam instant parser.
