The problem is the IAU 2006 requirement of clearing an orbit is extremely vague for scientific purposes. But I would expect nothing else from such a hasty and heavy handed effort.
Yes I’ll admit it’s somewhat vague and open to interpretation, sort of the way the difference between a mountain and a hill is. But it’s just a term we’re talking about, nothing else. At least it has some boundaries, and isn’t so vague that I can call my dog a planet if I want.
