Why CSV is not just for readability? I think RFC is sometimes too pedantic, that it let CSV can handle both plain text and binary files. COMMA is not just a COMMA, but a COMMA not in different environments. Why should we use the phrase CSV or Comma Separated Values just for RFC? CSV or Comma Separated Values are not only for RFC, but also for EVERYONE who wants to use this word or phrase. Pedantry sucks!
