I think we have seen enough examples to agree with the acronym in so far as that it has indeed comma's between the values. At the very least. In short, it used to be a nice and clean format. Back in 1978. But I think today we can do without it.
Double quotes are also to be considered harmful.
A variant of the CSV format is the tab delimited list, which I have first seen used with Microsoft's Work. Though doubtlessly it was in use before that. The tab delimited list is comparable to the CSV list. It also consists of multiple items per line, but here the items are seperated from one another by tabulation characters. Which makes it ideal as a seperating character.
