Somebody is forgetting about Turquish B737 approaching Schiphol or Asiana B777 approaching SFO.
Not really.
On the Turkish B737:
What do you expect to happen when the autothrottles pull the throttles to idle on an above the glideslope approach-but not for the reason you would expect.

By the time the crew finally realized they had a problem and forced the throttles up, it was almost too late. When the autothrottles then snatched the throttles back again, it was too late.
You have to watch your airspeed on approach. You really cannot delegate all the responsibility for watching your airspeed to the systems. You must monitor and control airspeed. Insufficient power on approach means you are going to be landing short. Same goes for Asiana's 777. Different reasons for insufficient power, but same short landing result.
These were not primary stall accidents, even if the crews got to some high AOA in attempt to buy air time.
