[Suggestion / Feature Request] 1.18 World Update

Hello,

Not sure how or if the devs plan on handling this, but I just wanted to share my ideas when it comes time for the 1.18 update. Considering the changes to the world height and depth, I hope it will still be possible to update older worlds to the future 1.18 version.

If it will be possible to bring over older worlds, my suggestion would be when updating to replace the current world's bedrock (around Y level 0) with deepslate. Anything below Y level -1 would be fresh new underground generation. This would be awesome for anyone planning on keeping their old saves - it would not be necessary to travel to new chunks when one could simply dig further down. Hopefully this would be possible to code in the world update script, I don't want to lose all my builds by having to create a new world! (or by having to move far away to new chunks).

Best regards,

Tom

    I have a few creative worlds that I have been building in for a few years. Two of these are city worlds, one modern, and one futuristic. The first one is a deep ocean flat world with bedrock, stone and water. The second one is a normal flat world desert with no generated structures other than the desert wells. It would be useful if I could choose, the first time I open these worlds in 1.18, how to extend the world from y=-1 to y=-64. I want to replace the bedrock (y=0) in both worlds with stone (maybe deepslate), fill this same block down to y=-63, and then make y=-64 bedrock. I may be interested in generating ores, etc in this new area, though unsure. The key here is that this takes effect for all existing chunks, and not just new ones. I could also add that these two worlds really need at least blocks up to y=511, but that’s another discussion.
