I have a question about how it will work MCP Reborn with new minecraft version numbering (Year.DropNum.Hotfix). It will also be very interesting to see how it will behave after the obfuscation is completely removed. 🤔🤔🤔

after the obfuscation is completely removed there will be no need for mapping/remapping anything at all

That's certainly true, but I think tools like MCP Reborn will still be necessary, as they simply make it easier to view code, as well as edit and compile it.

MCP Reborn is more convenient than opening some GUI tool for decompiling or using decompiler's cli so yes I agree with you. MCP won't be necessary because you can just decompile it like you would any jar but it's definitely more convenient.
