A lot of default wallpapers gone on iPadOS 17

After updating to iPadOS 17, most of the default wallpapers on my iPad have disappeared. I can't find the iPad Pro M2 default wallpaper and many different wallpapers that were there before the update. I heard that Apple removed them, but I still don't understand why. The iPadOS 16 wallpapers were very good and Apple just removed them. Now there is only one nature wallpaper, but there were many more before. It would be very good if Apple decided to bring them back.
