It sure would be nice if dive computers gave an indication of when the controlling compartment starts off-gassing. The information is there and just a matter of providing a simple display (Icon or flashing indicator). Other than intertrupting an ascent that could be too fast, deep stops seem to be counter-productive if the controlling compartment is still loading. I would not mind seeing what compartment is the controlling compartment as it would provide a basis for planning the duration of a rest stop but that may get a bit complex both from a display and a user response aspect. Probably more than most divers would want to know or have any idea what to do with it.
I'll make a WAG and say a deep stop won't do much for you if your max depth is 16 feet or less.
