Floating Islands is janky

The Floating Islands world type is a little bit broken...

If "Generate Structures" is on, I can see villages spawned in that are sitting on thin air, and some janky world development which looks like someone took a hole punch and put a hole through a cave. I know that this is early, early 1.18 but I didn't even spawn in on an island... seems like a simple fix to me to at least get a spawn location right.
