Well, it was not actually meant for your situation, & no you shouldn't ask them about it, we already know what they'd say. We often cite examples; sorry I offended you.
Concerning your situation, I pulled inspection permits on every job I did & I always run the new whip from the disconnect, never had a complaint by an inspector; every contractor I knew did it.
Perhaps some codes don't allow it except by licensed electricians; as long as it's done in total accord with the code, I don't see the need for a code adding the expense of a sub to do it; it's very simple on residential jobs. IMO, the HVAC code inspector should be required to check the electrical as to code from the main breakers.
