If he choses to wander off and make his own decisions that are so far above his pay grade, then it's no wonder in the past so many buildings have failed.

There are reasons why 1/4" Per foot is in the code, and it's not to see how many people can ask for exemptions. The reason code officials do things such as this is mostly due to unfamiliarity with the code itself, and why this design slope is incorrect.
