I think it is the same reason for the lack of... with PRISM divers, Both companies have divers who dive mainly Recreational limits or average between 150 ft or shallower on most dives.
Actually Martin, sorry to say that there have been 2 fatalites while diving the Prism, one was a friend of mine. But both appear to have been medical issues. Equipment was recovered and working properly.
And as for the habits of the users, most that I know are tmix certed and doing plenty of deep stuff. There are plenty doing deep stuff, including a team of working divers who regularly do dives in the 600 ft zone...
