If there's no driver then it would take effect right away. This causes problems for devices during startup -- the period of time from device discovery to driver binding is long enough (because there's so much other activity during bootup) that the device can autosuspend before the driver is there to prevent it. For well-behaved devices this wouldn't matter. But unfortunately there are lots of devices which break when they suspend. That's why level = auto is not the default.
