My take is that comma separated JSON could come in handy

(1) when dealing with huge data volumes when streaming is needed or memory restrictions apply or

(2) when CSV does not work because there is no common standards on how to deal with special characters, empty lines and the like.

But then, in case (2) I could also just use JSON if the set is not too big. So, that really leaves (1) as the most important use case. Or did I get this wrong?

Nope, that's pretty much exactly it. It's the one thing JSON struggles with and this seems a good aT to deal with it and in a way that's still quite user friendly
