Client-agnostic Minecraft Server

• Come up with a better title, yeah?

• ViaVersion might not be the best solution
• A from-scratch Minecraft Server might have a better option

• I don't plan on making this, but I think it could be a good idea

• A service that provides client-abstraction, basically a unified model of what a client is that a custom Minecraft server could build around rather than being tied to a single version and using ViaVersion to crudely translate packets.
