At first, I thought you were being flippant, but then I realized in horror that you were serious.

While I know you were coming from a good place -- I'm all about automating a testable problem (i.e. TDD, write failing tests first), and I think in the right hands, this would be a nice tool -- I could only see SO using this to further enforce strict requirements in what they consider a "valid" question.

"You must set up a lab environment that fully replicates the issue in question."

Maybe they wouldn't let it go that far (I would hope), but I think it would head in that direction.
