<shrugging>we change it? I am not happy at all with that approach, I know it could be a future maintenance mess. And I would have much more preferred to set a bit in struct usb_hub. But as I said above, going from struct usb_hcd to it's root hub 'struct usb_hub' is not trivial (or I am missing something too simple).
