Camels walking on Quicksand

Camels are often used to cross harsh sandy areas, and in the Minecraft live trailer it showed Camels being used to cross powdered snow, and I think the same could be said for quicksand and sandy areas. These new quicksand blocks would work like powdered snow, but without the freezing debuff. They could be walked on by husks, rabbits, and camels the native mobs to deserts. However the player and other mobs would sink or be slowed by the thicker sand. I think this would be an interesting obstacle near desert temples, and throughout the desert to make them more challenging to traverse. It would also add more reasons to have a camel!
