I wouldn't argue with that. One could also say it's a good thing though ... if you're modifying the method enough that you need to rename it, those original files might not be valid any more, so it's a good thing if the tool wants to recreate them.
I think, that would be a stretch to say so - in my opinion, it's not a good thing for the sole reason that it doesn't let you opt out of it. And it's not one of those cases when you would want to enforce discipline because renaming a method doesn't have to do with its contents.
