If I were sitting on a thing that could decrease bugs 1% I'd be really excited. The only reason this looks like a paltry reduction is that it's hugely expensive and difficult to change languages midstream. This is evidence against a shop retraining C++ devs in Haskell (which I'm sure someone somewhere wants to do). But if it was something like switching editor fonts? I'd do it for 1%.
