Dave, 586,
for info BAe 146, Avro RJ, DH 125; every production aircraft was stalled clean and as configured for landing.
Risk was managed by fitting a stall panel for comparing cross side AoA vanes and airspeed; this could be used by any operator.

Flight test / certification involved much deeper investigation, extreme manoeuvres, and harsh pilot handling.
High risk flights had additional display and recording of AoA; the aircraft was fitted with a stall recovery parachute. Crew wore parachutes, cabin doors could be jettisoned for escape.

re-certification of the Max probably ranges these types of flights depending on what is claimed for flight with MCAS inhibited - AoA lockout, unreliable stall warning and speed (ADC), reduced stability margin and different feel gearing.
