It isn't that easy also. There is a lot of code that uses 
interface contracts. It would require a few yeas deprecaction 
period during that the bug still exists. And disabling it for the 
interfaces just postpones the problem since it remains for the 
classes. And removing it for classes and interfaces would destroy 
one of the nice D features.
