The issue is the server doesn't use plugins since they had lots of issues after each update while using plugins and the maintainers decided it wasn't worth it to maintain that. So as is it only has a script to minitor chat for commandts like :home :spawn :warp etc. and is otherwise completely vanilla.

There are some downsides like that villagers don't breed but they also do give out spawn eggs and occasionally spawners, so it's still reasonably easy to renew villagers. Big downside is that farmers can't replant crops, so all crop farms are manual.
