Just thought I would add my 2 cents worth. One of my sons is in his first year of a diploma in photography here in Melbourne at the Photography Studies College http://www.psc.edu.au/ in South Melbourne.
Thus far all photos the students take must be in manual exposure and manual focus. If they submit a frame to be assesed and it is found to have been taken Av, Tv or any thing else, they have to go away and do it again.
An interesting discussion none the less.
