These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Dc One Million
Bizarro Episode: Hitman One Million contributed absolutely nothing to the plot and served to only show that only Garth Ennis could see that the great, optimistic future of the 853rd century is filled with Jerk Ass, useless superheroes.
In fairness to Ennis, while most tie-in writers got fairly detailed plots from Morrison, his merely said "Garth: do a pisstake."
And "Jerk Ass useless superheroes" does describe some of the "icon jockeys" who showed up in the other books, like Aqua-Fresh and Negative Gorilla Woman.
