So I am requesting a plugin that is a forge/fabric mod but doubles as a plugin:
Quote"If you're running a Spigot/Paper server, you can support players with the client-side mod as well - just throw the fabric jar file into your plugins folder. Yes, beenfo-1.16-fabric0.13.1-1.1.jar is a Fabric mod and a Spigot plugin at the same time, and will work with clients with the mod, no matter if they're using Forge or Fabric. For 1.16.2, use beenfo-1.16.2-fabric0.17.2-1.1.2.jar"
Quoted from: https://www.curseforge.com/minecraft/mc-mods/beenfo
The team has already uploaded Beenfo for the forge software.
I asked the developer, Giselbaer, if they could submit a version for 1.18.1 to the spigot website and they responded fairly fast:
https://www.spigotmc.org/resources/beenfo-spigot-server.98953/
The mod/plugin has almost 700k downloads and constant support from the developer. The importance of this being uploaded is so that people that have the client side mod can use it on the server. (It's a vanilla server but I am running client side mods)
Please consider my request. I love your services and I'll understand if you don't want to have this inclusion. 
I already tried the suggest link and it wasn't popular enough. (Probably because it was just created on spigot)
