It allows each line to be completely independent of it’s neighbors; you can comment and/or add lines without needing to touch neighboring lines. Also, it makes it visually easy to spot missing commas. Give it a try sometime, it’s actually quite nice.

Wouldn't this also be solved by allowing trailing commas?

But they are not independent: first line doesn’t have one.

Also makes nice file diffs!

Wouldn't the same thing occur if it wasn't there at all?
