What if you need to file a bug? What if you have a question on the config that's not easily answered by the docs? If you never, ever find bugs and never, ever have questions, then sure, separate the two. There are genuinely people like that, but they're not common. If you're one of them, then I'm genuinely glad for you.
My opinion is this: You use software. You don't use people, but you sure as hell rely on them.
