I've been playing on a server running Linggango for a few days, and had a few suggestions.
First is Utilitarian, mainly for Snad working well with source generation due to the absolutely source hungry Adam's Ars Plus, but there are other nice QoL features as well: https://www.curseforge.com/minecraft/mc-mods/utilitarian
And the other is the Relics and Artifacts Compatibility mod, which simply makes the Artifacts behave like Relics with the leveling system: https://www.curseforge.com/minecraft/mc-mods/rar-compat/files/7106942
I do not believe either has too much of an effect on server ram, but I could be incorrect.
A bunch of different functionality, neatly packaged in different modules that can be disabled and enabled depending on the users needs. Also has an angel block, snad, fluid hopper and a redstone clock.
