Note the qualifier: “not an Internet standard” (my emphasis).

And again: None of that matters. I am not talking about formalities here, I am talking about technical realities.

Whether it is formally called a standard or no doesn't change the fact that this is the document everyone points at when determining what CSV is and is supposed to look like. So it is de-facto a standard. Call it a "quasi standard" if that makes you happy.

Oh no; I agree with you completely. I just wanted to point out that the document does not disclaim being a “standard”, is just says that it is not an “Internet standard”.

My mistake, in that case, thank you :-)
