In the short time we got to use shulker chests I found them to be the single greatest addition to minecraft in a long time.
It significantly reduced the chest clutter and storage area in my base by allowing me to condense down huge stores of items. It also allowed for easier transfer of large quantity for trades or large building projects. They also significantly improved and expanded my ender chest storage ability. I feel a special villager trade needs to exist only at spawn to control the price and protect the economy. If a fair price was set say 1 diamond per chest like Cephid had done all who want them can go mine diamonds and purchase as many as they want. Being that you can purchase them for a set price you would stop someone from going into the end collecting as many as possible and then gouging the market.
So by adding aspecial trade you wouldin fact protect the servers economy while making these available for all to use. Ifthey were added to crafty crates the potential for price gouging still exists so a special villager trade is the best choice.

please consider adding this because it really excited me to play minecraft again with this update addition. thank you

I disagree with this suggestion. Shulker chests are indeed good at reducing the clutter but they are also powerful. Players with enough shulker chests can hide all of their base in an echest, which makes it really hard to get loot from raids. That is a good thing in my opinion but they are supposed to be rare. I believe that only the players with enough resources should be able to get them from end or buy them. You will need a good set of armor and probably a flying machine in order to get shulker shells regularly. Or you can buy it from other players but it will cost you diamonds. That is how it's supposed to be!

We should be stopping this kind of request of adding special villagers. As pointed out in many threads, this OP/special villagers deviate and cause imbalance to the game. Shulkers are meant to be rare and you need to explore the end to get them. Just think of it as a late-game item, therefore you need to prepare yourself in order to get them.

I don't agree, either we do custom villagers or we do not.
Shulkers chests being common was one the main issues of the current map, its designed to be a rare item

We don't plan on adding any non vanilla trades. And part of the economy was really messed up from the shulkers since we had no idea how OP mojang was going to make them. Go to the end and get shulker shells .
