In over nine years of playing Minecraft and monitoring this forum I have never seen or played a world that spawns you on or even has an island with three villages so close together that you can stand in one spot and see all three.
Here are the Minutor views of the island n both 1.15.2 and 1.16.5.
I've checked that the island exists as far back as java 1.10.2.
Notice that the 1.16.5 version has a shipwreck on the sand bar north west of the main island.
Both versions have caves that go nearly to bedrock.
Both versions have most all types of domestic animals.
EDIT: Just loaded seed into 21W05b. Island with three villages all in view of spawn, and the shipwreck on the beach. The wide map for this world looks diverse. Looking forward to exploring this world this evening. Thanks for sharing.
