It's not going to happen because it doesn't make any sense and like pdnnoob says, you're using existing features incorrectly in the first place. An additional "why not" is because features don't just get granted by the Feature Fairy. I have to actually spend a lot of time designing and implementing, then testing and validating them. A feature must be generally useful for a wide range of people, and this one just sounds like it adds confusion and complexity. It's not like saying "please! why not?
