I had the pleasure of meeting Doug Dix at a show in Arizona this past weekend! I also attended two talks he gave on Uromastyx Breeds and care. It was good to learn from someone who has the education (PhD in Biology) and experience, the research background, connections, and success that he has. I asked him his opinion regarding the soil substrate, and he didn't think it would be a good idea, especially for cleaning. Of course, he has a lot of animals to care for, more than most of us. Also, as to the rate of growth of juveniles, sure you can get faster growth by overfeeding, not brumating. Many breeders do this. But research has shown that these animals do not live as long and are not as healthy in the long run as those that are grown at a more natural rate. (I also know this is true for tortoises and turtles!)
So, after purchasing a beautiful pair of yellow Saharan yealings, I will be totally changing my habitats yet again. I have noticed that the soil does dry out very quickly, and yes it does collapse on them. So why risk it? I can't see pouring water on them every week!
