The problem is even if the interface says it's not activated, can you believe it's not activated? When you have closed source software running on a separate chip you have no control over you can never be 100% sure of what it does. Even if you trust the company completely you can't be sure there's no bugs in it. Especially if it's got a load of code your "not using" in there.
