ends up having that extra -/+ pair of lines just to add the comma

That leads one of my two reasons for using it: It's easier to add a comma at the end of the line you are typing than to have to modify two lines (instead of one) when adding a new item to the list.

(The second reason is that I think it looks better with the comma.)
