Permanently add the endlessly generated dimensions from the April Fools 2020 snapshot (infinity snapshot).

Also add this to Bedrock.

There are 2 ways to balance something like this, either add a toggle on the world creation menu or use the inscription table idea (see further bellow).

It would be a good way to have a greater access to some of the rarer blocks in Minecraft, or some of the blocks or items usually unobtainable in survival (i.e. spawn eggs and mob cages could be found in chests).

This being said super rare or expensive blocks, such as netherite or diamonds should be exceptionally rare so that there is some form of balance.

Also the dimensions should be less chaotic but still weird and remove the joke dimensions.

Accessing the infinite dimensions should be an end game feature, requiring the player to make a new block called an inscription table, this should require at minimum; Netherite, End Stone and an Enchanting Table.

To use the inscription table you need a book and quill and a certain amount of levels, write and sign the book from within the inscription table and then throw into a Nether Portal.

Thanks to zKaitzo and other commenters for some of these ideas, also please read their comments for further information.
