Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Server-side mod: Kiln runs mods' code on Horizon's single-player server, not on dedicated servers.

In the author's words

Stops known hostile connections before they reach Minecraft, saving your server's resources for actual players.
