It could be set to a low value, but it shouldn't be set to 0. There aren't too many things you can do with an unbound device; lsusb is one of the most common. On the other hand, we already have a usbcore module parameter for specifying the default autosuspend delay. That's what the delay is set to when a device is first initialized, before it is bound to anything. Unfortunately the parameter's value is in seconds, not milliseconds, so we can't set it to any positive value smaller than 1 second.
