Having been caught out in Tucson hailstorms with a 0% precipitation forecast, I'm not much impressed by "L5 for some regions, sometimes" myself. L4, sure, map easy suburban spaces carefully and wake up your driver if things get weird. But L5 is intended to be human-parity, or at least have well-defined boundaries. It can give up and park until the snow stops, but if you're taking out the steering wheel it had better not stop more than humans do - and offer a "chance it anyway" button for if the snow isn't stopping.
