It is better to think and not do things mechanically, and that's exactly why
people add the trailing comma.

If you do things mechanically, you may leave out the trailing comma, because
it certainly isn't necessary.

If you think about making your code maintainable, you will look for ways to
prevent mistakes when people edit your code later. The trailing comma helps
prevent mistakes, so you'll use it.
