Contrary, I think that a high risk of misuse is an important argument 
weighing the value of a feature.

This way, for example, the last generation of programmig languages do 
not include pointers or restricts them (even C++x will ban some use of 
pointers) preventing their invalid, unsafe, unsecure use.
