Structures to hint the end and show how to craft golems, wither and beacon

A new player has no idea that the end exists nor how to get there. With ruined portals, Mojang has done a great job to show there is another dimension and how to get there. So I came up with some ideas:

In caves could be abandoned structures (like the stronghold but smaller). Let’s call them Wisdom’s catacombs.

In set structures you would find pots with symbols of blaze powder and ender pearl to show the crafting recipe of an eye of ender. 

In Wisdom’s catacombs you would find hints how to craft golems. There could be a stone block with a pumpkin above for the copper golem, a stone T for the iron golem and a I for the snow golem. In chests near those you would find some copper, iron and snow.

In a darker and rarer room could be a hint to craft the wither. Some parts of the T of soul sand with pots on top with the symbol of a wither skeleton’s head. In the same room would be some obsidian and glass to hint the crafting recipe of the beacon.

Behind the withers room you find a hint how to use the beacon. This could be shown with a pattern of stone on a wall showing the form and size of the pyramid. Iron (and when lucky a dia) in a chest to show the material. At the beacons place would be a pot with the symbol of a wither skeleton’s head.

Lots of suspicious sand and gravel and some bone blocks would be in this structure too.

Books placed around an obsidian block to hint how the enchanting table works. 

The structure would vary like trial chambers do but would generate more frequently.
