I think older people who played Bros 3 in 1989 and World in 1991 + watched the cartoon, are quite happy with the koopalings, but if your first Mario was 64 or Sunshine, it may seem like a wasted slot to you.
Before Miyamoto decided to create Bowser JR and retcon him as Bowser's son, everybody thought the Koopalings were Bowser's kids, they even said that in the manuals. And that is why Bowser JR is so disliked by many.
I do think Baby Daisy, Baby Rosalina, the 2 Metal characters shouldn't exist, and the game would be half a point better if they were replaced by Diddy, Kamek, Birdo and King Boo.
