It's a very different type of aeroplane, but I used to demonstrate this type of stall to Air Cadets learning to fly the Venture motor-glider. The stall scenario to be taught was the classic reducing IAS, buffet, and nose-drop. But I liked to demo also a more subtle stall where you end up with a reasonably normal attitude and power, but with the stick hard back, very low airspeed, and the VSI off the clock.
The only indications that you were stalled were the control column position, IAS, and the vertical speed. It was even a very smooth ride!
Simply releasing the back-pressure effected immediate recovery.
I suspect that simply releasing the back-pressure in this case might have been sufficient to recover very rapidly.
Having flown an aircraft type, of which two were lost to deep-stalls (HS 121), and several other types where the HS is not blanked by the stalled wing, I think the former were your worst nightmare. The latter could almost be likened, aerodynamically (and for the pilot-held-stall-condition) to those old RAF motor-gliders.
I realise that is a gross simplification, but few pilots (I suspect) were ever demonstrated the pilot-maintained stall.
