Escape the mandatory requirement of logically client only mods on the server. We players are free to install permitted mods!!!
It's quite common that some mods is imcompatible with each other, such as Emojiful and Modern UI. I prefer modernui much more. Considering emojiful SHOULD BE a client only mod (and it marks as such in the 'mods.toml' file of Forge), I disabled it, but then was refused to join the server because of its new registry entry (recipe type) of recipe for custom emoji. Fine, so I developed this mod, after all, I REALLY CANT DO WITHOUT modernui :(
I may add patches for more mods in similar situations in the future.
