The time saving isn't as important as avoiding frustration in your tools. Stubbing your toe on silly problems like trailing commas breaks flow and makes exploring less fun. In my experience, these commas don't add any real meaning to the human readers. Will it really obfuscate the code for a future reader? I can imagine it can look unfamiliar and consequentially grate someone's nerves. Reminds me of the arguments around R's "<-" vs "=". I agree with the sentiment for most code, but I doubt I spend as much time reading my SQL queries as I spend writing and refactoring.
