To begin with, why do you want it to be a feature, if it's so msvc-specific?
Do you want to build with different values of it? If not, using a compiler
options can be more reasonable.

I tend to believe that the validation can be just disabled. It's a maintenance 
nightmare to handle all cases where we should relax validation, like 
conditional properties.
