Ideas for Accessory & Trial Chamber (better loots)

I feel like accessories or something similar should be added into the 1.21 update, giving players a reason to explore the new trial chambers.

The trial chambers updated in 1.21 is really a great update for adventuring and exploration, but honestly from its performance in the latest snapshot, I feel like it is fun to play, but the loot is not attractive enough in my own opinion. All of the loot that's being found in the trial chambers are achievable at other places, maybe even being faster (iron stuffs became extremely easier to obtain since cave & cliffs update, diamond tools and armour is challenging but still easy obtainable through villager trades)

Therefore this feature could attract adventurous players to play for a while, but might be neglected by other type of players during the game, which is waste of such a good update.

A good solution, I believe, is to add something like accessories into the game. It doesn't have to be direct upgrade in power, damages and stuff, but could be improvements in the overall gameplay experience. Some examples of accessories could be:

• Double Jump/ Multi-jump Accessories: I feel like it absolutely fits with the trial cambers combat, since there are many high level platforms that requires player to block themselves up to, a double jump would greatly improve the combat experience.
• Further Reach Distance: Basically the concept proposed with the crab claw (mob vote), it would help players to build, also indirectly improving combat ability.
• etc.
