My $0.03 (inflation)...

Your point about smaller diffs and reordering lists is correct, and (I'm
guessing) what originally motivated this feature.

However, that motivation only applies when the items you are listing are
normally or typically placed on separate lines.

That's true e.g. for enum constants, but not for the other stuff like
method parameters, etc.
