Uh, ok, bad wording. It's more about easily changing the values during
testing so that I can use the refined code to deploy it. So it's about
ease of change during development, not in the production stage.

But it would be useful even for boundary testing. You can have one
central point to define a few constants and wont forget to adjust them
if you one day decide to change your code.
