Agreed. Without quick exhaust valves, you're forced to either halve the flowrate by running exhaust air back to the valve, or introduce some other mechanism to retract the cylinder - a complicated waste of weight.
I maintain that rules that discourage the use of pneumatics actually reduce safety. I would trust a factory-tested solenoid valve over a gerry-rigged latch holding back hundreds of pounds of spring force.
