Making achievements available after cheats

When setting cheats on a server main achievements should still be disabled however I've come up with a new idea that may or may not of been brought up before. After the activation of cheats the player like in the base game can basically do whatever but if they switch back there should be a new menu that makes it so to activate achievements for that server again they would have to return the amount of blocks they placed and taken from using cheats. Including this they should be given extra tasks around the Minecraft world to make them work back up to them instead of just having to easily regain them like if they were to just place a wood block. Anyone who thinks this is a great idea spread the word and vote for me and thank you for your time.
