My point would be that one effect of knowing you are overweight would be that you don't climb at what you think is the best climb speed. Whilst it is clearly more dangerous to be overweight, the most dangerous spect is to carry on as if everything is normal.
If people don't know the basic principles of flight effects of weight, then its a good idea not to go over weight!
The stall speed is not the only speed the moves with weight, best rate, best angle, Va etc etc all change.
And this obsession with teaching 'stall speed' and not 'stall angle of attack' obviously has serious ramifications when over weight.
