I like the "dwarf planet" designation; it makes sense to have it. The only thing that doesn't make sense is the IAU's claim that a dwarf planet is not a planet. Huh? A dwarf star is a star. A dwarf tree is a tree. A dwarf human is a human. How can a dwarf planet not be a planet? It says "planet" right there in the name.
So we should ditch this legalistic, nonproductive debate over planet vs. dwarf planet and just accept that dwarf planets are a specific subcategory of planets, just as giant planets are. Instead of saying our system has nine planets, or eight planets, or whatever, let's say it has four terrestrial planets, four giant planets (two Jovian, two ice giant), and hundreds (or thousands?) of dwarf planets.
