Make accessing the end more difficult

in my opinion and in the opinion of many people, the end is not that challenging to access anymore, I have an idea to add new types of ender eyes dropped from existing bosses in the game, such as: Warden drops the deep eye The guardian drops the oceanic eye The witer boss drops the nether's star, with it you can join an ender's eye and her in a smoothing table making a Celestial eye And the piglin brute drops the Nether eye all of these are thus necessary for entry into the end, placing them in the portal in specific blocks: the right, the top, the bottom and the left
