On winter rallies with enough snow and freeze you are able to use small forest tracks, or even frozen lakes, swamps and fields as a part of the route to make it more technical and interesting instead of just long straight after another. I hope they start experimenting more next year, or find more interesting roads. But I think otherwise everyone has been happy with the rally. I don't even know if watering would be needed since conditions seemed to be quite good (apart from second runs after historic cars, but that's not something even freezing could help?)
