As someone who's an idiot and doesn't know what they're talking about, how hard would it be to make Minetest compatible with Minecraft servers?
Edit: I recognize you're talking about 1st party Minecraft server development now, there are 3rd party implementations though, correct?
Presumably there would need to be modifications to the Minetest engine, but it seems easier than re-implementing Minecraft from scratch - and would be a great screw you to M$.
Minetest is not remotely close to feature parity with Minecraft.
IIRC, even local/singleplayer games start a server on your machine and then the client renders whatever the server tells it too - so it seems like maybe not as much work as it looks on the surface, especially with as well understood as Minecraft's client/server protocol is.
Also, the Xbox app is the only way I know of to do cross-platform voice chat when playing Halo Infinite.
