I put the notes field there to demonstrate to new users that cloze notes don't have to be limited to a single field. But when I think back to the clozes I've seen people make in the past, a separate notes field was rare, so I'm not sure whether it's worth including by default, as the user can always add one later. If you disagree, feel free to take the question to the forums so we can get more feedback.
