::::Where did Stern say that dominance was used to achieve the pre-determined number? I find that hard to believe, since it was Stern himself who made the division (uber/unterplanet) well before the IAU addressed the issue (and even then, the IAU started with roundness, not dominance!). The dominance gap is not just an idiosyncracy of our system but a consequence of the physics. As for "dwarf planet", there were few complaints about "minor planet" for well over a century. Similarly, for roundness, there were no petitions to reinstate Ceres to planethood. The previous silence on these issues shows that these objections to the IAU definition aren't about science, but the emotion of Pluto.
