"Original" World Generation Setting

The new mountains and valleys, gorges and rivers, are great; but for many the old generation can be nostalgic and they'd like to play with that type instead. It'd certainly be harder to make generation updates in the future but I think it'd be a lot more worth it than creating a fourth split between players. I'd love to try out the Wild Update with 1.17 generation, because all of the biome concepts were made with old generation in mind, not new ones, so it'd most likely be nicer.

So, let me get to the point - I'd like to have an "Original" world setting among with Amplified, Superflat etc. that when used, it has the old, pre-1.18 generation, but it can still have the new features from 1.19, 1.20, 1.21 and so on. Thank you for considering, that's all!
