Like ShinerB, I would like to see more testing of the rigs ability to safely go DOWN a long steep grade.
IOW how much un-braked towed weight can the truck safely handle going down a standard grade? And while you're at it, make it a twisty one with 20mph hairpin turns separated by 35-45mph straights, not just an Interstate.
But I imagine there are many issues in designing such a standardized test.
As Marty wrote bellow, the tests are already out there but not applied to pickups. They just need to put these little guys through the same vetting as the bigger trucks.

To a degree, the current specs are better than nothing. I do not see them as being realistic from what many of us would can reasonable. Even an 18wheelers setup for OTR work have stiffer specs than pikcumups with this rating! We will not discuss rigs setup to potentially go off road like dump trucks, local deliver garbage trucks etc. Top end is not as good, but 60-80% grades to be pulled....40degrees for those not understanding % grades. 100% is a 45 degree angle, ie 1 unit of rise, per 1 unit of run.
