If, as may appear to be the case, your "More than a few crews have forgotten to set the flaps for takeoff, then when the warning sounds off with application of takeoff power the crew wakes up and selects takeoff flaps and presses on with the takeoff." is correct, it appears that training and airmanship have failed - I have no other solution - do you? At least, stopping the 'cowboys', even AFTER a "a successful shoot-out" might prevent another from the same?
