Since categorizing something as a planet means nothing then traditionalist is the only way to go. If Mercury is in the same category as Jupiter and a sudden orbit change can mean a thing might no longer be called a planet then there is no scientific value in calling things planets. They are just traditional names given to fairly random objects like constellations.

I would personally categorize everything with a high enough gravity as a planet, i.e. everything that can hold an atmosphere or sth.
So, expansive then.
