I'm don't know much about development, so if my request is stupid forgive me. Since @Spottedleaf is on PaperMC it's kind of a bummer Starlight isn't available as a Spigot plugin. AFAIK Spigot forks are much more popular on servers than Fabric so a plugin would be much more impactful to Minecraft.

starlight isn't a plugin and requires fairly deep modification of the game which isn't supported in a spigot environment.
starlight already exists inside paper however

Ah, okay. Thank you for clarification and the work you've put in to this.
