Scanning the comments I don't see my reason for wanting trailing commas: version control. You want to preserve the history of your code and to be able to easily query your VC system about the providence of each line of code. I want to add a new item to the end of the list, I also need to add a comma to the end of the previous line. This makes my commit larger than needed and it muddies the code history. Just let me make simple incremental additions to a file as it changes.
