I know how late I am to the party, but here are some ways that Minecraft should be revolutionized:
Officialize mods, and make versions into mods (certain bug fixes should exist, but for “useful” bugs, make a toggle). Beta 1.7.3 could be the base/core.
Overhaul the rendering engine. An unofficial Discord server owned by Minecraft developers called “Vibrant Vanguard” says that they’re already doing this, and they’re also actively talking to optimization mod developers.
Recode in Kotlin. Kotlin is a JVM bytecode language, so it’s still compatible with Java, and has multiple benefits. This would also make the developers clean up code, making Minecraft more performant.
