If you don't use the "utility scripts" in your development environment, how
do you know they work with the code you're developing?  If production has a
completely different set of configuration files from your development env,
how do you know how your code will work when combined with them?

Any time there is a difference, there is the potential for bugs which you
cannot catch until you deploy your code, and that's a recipe for failure.

Minimizing differences between development and deployment is a *great*
thing.  There are certainly cases where differences are necessary, but
one should strive to make them the exception, not the rule.
