If the IAU had any sense they would have made Ceres a planet instead of axing Pluto. These decisions should be made in a way that makes funding exploratory missions as easy to sell as possible. Pluto the planet wis easier to sneak through congressional budgets than Pluto the Dwarf planet. Instead of waxing poetic on the Platonic form of planet, just draw a wide line around things people want to get probes sent too without going so broad as to lose the plot. Even better would have been to give Pluto a designation like the nearest Rim Planet, implying there are so many strange Rim Worlds for us to find and explore.
