Ceres is definitely dwarfish, but pluto is just smallish, moreA planet should be defined based on what it is not where it is.
plutoish.
Both planets nevertheless. Lane clearing my ass.

Ten Planets +.
It should also be defined as to how big it is, and if it orbits on the
same plane as the other planets.
Why in the same plane? We don't know enough about planetary formation to
rule out accretion in multiple planes. By the time you get out past
Pluto, there is more than enough room that bodies will not evacuate it's
surroundings and will spend billions of years without approaching
other bodies that formed 30+ degrees out of plane with it.
Size and that it in an orbit. That defines a planet.
