TSV is superior to CSVs, and it still angers me that Excel doesn't offer it as a standard input option, but your examples are fairly easily handled by eye in a text file.
Tools definitely make it faster and more reliable.
One of my first tasks as a junior dev was replacing an incorrect/incomplete "roll your own" CSV parsing regex (which broke in production) with a library.
Do people contain themselvs to a POSIX conformant grep subset in practice, or do you mean GNU grep that probably doesn't behave according to spec unless POSIXLY_CORRECT is set?
If a workstation has Git installed on it, which I’d think would be the case for substantial number of engineers out there (…not just software engineers), grep is there due to Git BASH.
(TSV FTW)
