Would it help to be able to explicitly suppress these warnings in 
certain regions of code? So e.g. could disable these 
warnings when iterating over enum members. Other code that is 
generic and cannot opt out of handling deprecated things could be 
expected to do the same. This shifts the onus from the compiler 
to the programmer. But given the complexity of the issue, it 
might be the right choice.
