Minecraft: Java Edition has been obfuscated since its release. This obfuscation meant that people couldn’t see our source code. Instead, everything was scrambled – and those who wanted to mod Java Edition had to try and piece together what every class and function in the code did.
Modding is at the heart of Java Edition – and obfuscation makes modding harder. We’re excited about this change to remove obfuscation, as it should make it quicker and easier for modders to create and improve mods. Now you won’t have to untangle tricky code or deal with unclear names. What’s more, de-bugging will become more straightforward, and crash logs will actually be readable!
surprisingly fantastic and consumer friendly move from mojang, good on them

Help and suggestions
My point is that literally nobody has been looking at obfuscated code for at least 5 years by now. All the toolchains automatically handle de- and reobfuscation transparently to the point that nobody has to think about it anymore unless maybe you are one of the like 3 people who is actually maintaining the classloading stage of a modloader, or if you are manually writing a bytecode transformer (which almost nobody has needed to do for years either, ever since tools like Mixin entered the scene).
For 99.9% of the modding community, and this includes most optimization mods, the only thing that is going to change is everyone deletes a line or two from their
build.gradleand continues about their day.As far as reporting things to Mojang: again, nothing changes here either, everyone who has ever set up a mod dev environment already has a copy of the deobfuscated source code on their computer, which is the only thing they are looking at when inspecting the minecraft source code or making changes to it. There have been reports on the issue tracker with actual suggested code changes basically since the issue tracker became a thing.
Okay - I am a bit of a dreamer, but I hope that Mojang dropping the obfuscation side of things is a sign that they are interested in working more closely with the community.
Of course, if I were to put on my pessimistic hat, I might think this is a move for Mojang to distance themselves from the Java edition as it’s likely that Microsoft thinks from a business perspective focusing on Bedrock is a better deal.
