A “ploonet” would also meet the qualifications for being a “dwarf planet”. Why do we need two terms, and how can you tell for certain that a dwarf planet is not actually a former moon? Pluto could be a former moon for all we know. So could Ceres.
I’m starting to think astronomy as a science is becoming like modern gender studies, full of fluid definitions depending on how you feel. The problem is, we all feel differently. Who, then, are we forced to discriminate against? Those who whine the most, not those who know the most.
