AS an MD80 driver I can say:
1. Stalling in a clean configuration is very rare. You have ALFA SPEED protection with the A/T that would not let you stall. But if you flight it without A/T, then you would be not such a good pilot to stall it in a clean configuration.
2. and the most important reason. Mostly take offs and go around are made with midslat, and in the case of a w/s and a sudden lost of speed, the auto slat will give you extra protection (It happened to me in the real world, taking off and encounter w/s at 300 ft, the speed drops and the autoslat actuated, giving me margin till recovering.)
I guess this case is what the autoslat was thinking for. ( like ZeroThreeLeft posted about the 727)
