I voted yes, but its a reserved yes.  The system fitted to the new Scubapro bc is a drysuit inflator, nice and simple to inflate, and you then use a standard pull dump to, er... dump air.  Stops the hose floating in your face and generally just getting in the way.

Now the No bit.  The pneumatic systems fitted to the Mares and Dacor stuff,  never catch me with one of them.  You run out of air underwater and start an ascent, how do you use your dump if it needs air to operate the dump?.  Too many newly trained divers I see dont know what the "thing with string" is anyway and in an emergency is not a good time to find out, just dont trust the idea of them, probably a reaction to the whole HUB issue.
