It's official- No snow depth

I'm very confused with the reasoning behind this. So, they tried and it didn't look good enough and that's why they decided to ship the game with flat snow? How is flat snow better than "not that good" deep snow? And why didn't they at least try to do it just on the roofs or something? And how can they say these are the best seasons ever when there's no snow depth, essential for immersion?
It's not a deal breaker for me and I didn't need a confirmation for what was already very obvious. What bothers me, as most of the times with this game is their answers, their explanations.
