Add The Unknown Block back

Back then you could use commands especially /setblock ~ ~ ~ unknown for the Unknon block. The Unknown block is a dirt texture with the word “Update”. I don’t need you to put it back in the inventory because that would be weird because it is normally a secret block only with commands. Now in the new updates it’s still in the files but you can’t put it back, please bring it back, I built a city out of those blocks and it’s all gone. Please Mojang!🙏
