Looking into the issues: "Add multiplayer support" The only reason I see running a minecraft server is to play multiplayer, so I guess there still is a lot of work to do.

"World Persistence" too. Although to me it's pretty useless without mod support which would be very difficult to do since Forge/Mods are all java obviously.

But a neat side project. Wish them luck.

Since it's distributed, maybe mods can be handled as microservices. Then it wouldn't matter the source language.
