You said it would be "needed". Now you just talk about how people "like
to" classify. Which is it--a need or a want?

Why so rude? Not a good way to repay someone who answered your Jupiter
question, after all.

You ask your question as though there were a sharp dividing line,
especially when it comes to non-physical needs. If you want to avoid
having this same discussion each time a new significantly-sized body
is discovered, then yes, you'll *need* to have such a definition. If
you don't mind it that much, then you may only want to have one.
