It boils down to gut instinct again, since there is no clear line of how much complexity to accrue before splitting something up. I think he likes to keep Linux in one repo because that makes it easier for him to watch the project and manage it. Currently, if linux gets separated into 10 components, Linus will still have to keep an eye on all 10, so from his point of view, complexity is still the same, or worse. But if he could actually let go and let someone else completely own another component, this would not be the case. Bottom line is that he is smart enough to be able to do manage a repo that large, which only proves the author's point.
