I like the Womb being deeper. It is harder to clean that way but I don't think many people would want to see that pool reduced to a waist deep pool for the sake of easy cleaning. I also like the natural contours of the Womb's bottom even if they are not totally accomadating in all areas. Having a shallower cement, or rock and cement bottom would make that pool less appealing for me. AZ, your suggestions do have advantages as you point out but I think the majority of folks would prefer the Womb to remain as it is. I don't think the USFS would support such a project either, even if it was something the majority of people wanted.
