Eden wants to beef up the royal rota. He was worried about not having enough royals to cover all of the patronages, and I have to admit so was I. The strategy of quality over quantity has been working, so the York princesses don't need to be called up. Really, they most likely prefer to stay second tier. While they would never go out on an appearance and act like they were being put upon, there's nothing to suggest that they wanted to be front-line.
