I've always wondered what it'd be like if Kingbdogz just rocked up one day and was like "Nup, that's it, the Aether, vanilla, now." and just pumped out a new dimension. It most likely wouldn't be a carbon copy, but would be similair. And I doubt he has interest in a mod he made as a teenager being a part of modern day Minecraft, so I'm here to guess lol(edited)
I have quite a big update set out for one last version on 1.19.x and then I will be updating that version to 1.20 and probably 21 by the time I finish the last few features
