Improved Trades with the Wandering Trader

This post is not duplicated as is purely aimed to the items of the Skyblock One-Block community and also to some items regarding superflat worlds. The items listed below are currently unobtainable in One-Block Skyblock and could be introduced as tradeable goods from any Wandering Traders while preserving the authentic Minecraft Vanilla experience:

Sunflower, Lilac, Rose Bush, Peony, Glow Berries, Sweet Berries, Glow Lichen, Mycelium, Sponge, Dead Bush, Spore Blossom.

I understand that sponges could be controversial since including them in the trades might reduce the incentive for exploration in a standard world. However, I believe some of the trades offered by the Wandering Trader already reduce a little the exploration.

Also this would make renewable the Sponge, Dead Bush and Spore Blossom.
