It would be great to have this Mod on Minecraft 1.20.4 for NeoForge.
I can't find any simmilar mod which allows me as Modpacl developer to inject a DataPack by default on world creation.

okay sorry, I have found OpenLoader to do this for now.
but your mod seems to have some great features which OpenLoader does not offer.

Forgot to close as a port exists https://www.curseforge.com/minecraft/mc-mods/drp-global-datapack/files/5359520
Future port requests will be closed without a comment
