One of many here who used to, but haven't in many years. Funny story - back in the young-and-dumb days, I first tried footing using the deepwater start with feet crossed over the rope. Problem was, I didn't have a wetsuit and failed to consider the effect of water shooting up my back between me and my life vest (circa 1980's vest that was as snug as I could get it). Dad hit it and I went straight down. Mom was panicking in the boat because I was gone and the rope went straight down off the back of the boat. I don't know how deep I was when I let go, but it was pitch black and it took a LONG time before I could even see light as I floated to the top. Glad it was deep water at Shasta!
