I can see both sides to this, but I'm only commenting here to ask a question: What would constitute a 'major' or 'minor' character? I know we all have concepts of these in our head [Harry, Ron, Hermione versus Pansy, Parvati, Colin], but what would the rule be for splitting all of the characters into one of these two categories? Like... a character like Bill - he doesn't have too big of a part in canon, but would you call him a 'minor' character? Also, someone like Lily - a HUGE character in the books, but not featured in canon enough to have a really solid foundation off which to base her characterisation.

So... just curious. I think drawing that line may be more of a challenge that it seems.
