I got bored of it pretty quickly so I didn't spend a lot of time on the island but some issues I noticed were:
Weather was almost completely static, temperature barely changed and no rain ever. Flashstorms still happened and the entire island would just burn.
Hunting camps and other world sites would spawn in skyspace but if you visited them it would just be another default planet map.
No raids, there were some insects in the caves on this island when I first landed so maybe infestations happen but I wouldn't know.
Biomes on these islands would change every time you reload the game.
No way to generate new sky islands or control where they spawn on map creation.
