Allay Support during adventures (Crafting, Potions, Shields) and Storage.

As someone who likes going into adventures with Allays, I think it'd be fun if Allays had minor functionality whilst holding certain blocks or items to act as support entities. For examples:

• When holding a crafting table, sneak-click the Allay to use it. This could help with creating blocks of ore during travels, reducing the amount of inventory space used.
• When holding a splash or lingering potion, if the player they're linked to has a potion effect run out, the Allay will throw their potion at them. Could also work with Healing, Regen or Fire Resistance if they catch fire.
• When holding a shield, the Allay will generally fly closer (unless detecting a dropped shield or attuned to a note block, wherein their usual behavior resumes), occasionally deflecting hits from projectiles.

• Maybe Shulker Box functionality? But that may be too overpowered. Def not with Chests or Ender Chests.

This would incentivize players to keep Allays around them during travels and alleviate the inventory during the pre End-game just a little, and reinforce their roles as companions.

In addition, given their lack of teleport as with Wolves and Cats, it might be good to add a way to store Allays in the inventory for when they're hurt or in a tight corridor as with Axolotls in Buckets. Sneak-clicking with a Book or Paper perhaps?
