I am quite sure you are not planning on updating the older versions, but I have a server and play with this mode everywhere I can, and I have seen a fair amount of 1.18.2 servers having this mod.

The 1.20.1 version has lots of features that would fit into the server so well, but we only get cheese, beer and fudge

so please, i doubt downgrading the features would be, if anything, a hard thing to do for the makers of this mod

We don't have the code anymore + im genuinely not interested :P
