I think it worth remembering the difference between recovering from an incipient stall and a developed stall.
Forgetting power changes which take time to attain ...
If the incipient stall is caused by too high an AoA, lowering the nose will bring about a recovery. If the stall is due to a low airspeed, say after a zoom climb, a moderate amount of nose down may be required.
Once that stall has developed, a considerable amount of nose down will be required to reduce the AoA.
It strikes me that +5 degrees NU and TOGA does not cover all eventualities.
