> The current definition of "planets" and "dwarf planets" is fine.

It’s serviceable, but is it ideal?

What’s the scientific advantage in categorising “planets” and “dwarf planets” as two separate categories, compared to unifying them into a single category (possibly while retaining the distinction as two different subtypes of “planet”)?

Which system would be more scientifically useful? Which would be more parsimonious?
