All Blocks/All Items Advancements

Perhaps we could see advancements within Minecraft: Java Edition (alongside achievements within Bedrock Edition) for obtaining every block and every item within the game. Both of which would be separate advancements/achievements, one advancement/achievement for obtaining every block in the game, and one advancement/achievement for obtaining every item in the game. The names of said advancements/achievements could be up to the greater Minecraft community or up to the developers.
