Everything you write except the full stall is exactly what is mandated under EASA regs in ORO.FC.220/230 and has been for two years; full upsets, classroom stuff and mandatory instructor training. It is an operator requirement primarily because for licencing there is no mandatory recurrent training, so to get it in the recurrent they have put it under the operator responsibilities. It comes into the initial TR course this August - again, sometime before I believe the FAA are mandating it.
The reason for not including the full stall training was the lack of suitably qualified sims. It is proposed to be included as soon as they are real. Boeing and Airbus tell us that will be some time, although apparently Gulfstream have already produced a data package. So I think the FAA person you quote was talking BS
