Adding hints towards certain mechanics?

I usually don't find myself using all the mechanics Minecraft has to offer, so I think adding something to hint towards certain mechanics would be a nice addition. Structures like the ruined portal and the secret Redstone room in the deep dark already hint at how to get to and survive in the nether and Redstone respectively,  so why not add more similar things? They could hint people towards how to brew certain potions, how to get to the end, how to make tipped arrows, what enchantments do, etc. It would help out new players, or players who haven't fully figured out how to do those things so they don't have to rely on google or tutorial videos for them.
