I think that 'clearing its orbit' standard won't survive. Say we find an earth-sized object out there past pluto, or say a jupiter-sized object around another star, the fact that their orbits are full of other tiny objects won't matter. If it is big enough, the other technicalities will fall away.

A rogue planet orbiting a galactic core, or massive BH, would still be called a planet despite in no way clearing its orbit of anything.
