No, I just wondered why 'nousb' disables on the runtime ehci/xhci (also included statically in the kernbel binary) while not other USB-related modules. Maybe it was thought that no downstream modules will load because of unmet dependencies ... but looks usb-storage can load fine without them. The question is whether there is any module at all capable of using usb-storage while ehci/uhci/xhci are NOT available. I don't have that much a problem with the behavior as it is now. ;) Just FYI that it was a bit unexpected to see it loaded at all.
