Trade mechanism for crafting recipes

Hi Guys!

I was wondering why poe does not have a trade mechanism for crafting recipes (bench & harvest)? Is there a specific reason why ggg has not implemented it?

I am fairly new to the game (around 350 hours of game time) and one thing I struggle with a lot is not having the recipes while crafting. I recently found out about the forbidden trove discord server where one can contact sellers for recipes but the trading seems complicated; contacting the seller and then trusting him with your expensive item while you get to keep his item as "deposit".

My idea is to have a crafting bench in hideout where you put in your item (not removable by the other person). You also put in the currency for trade in a separate slot. Meanwhile the other person selects the respective recipe(s), which you would see in the bench. You click the recipe and apply it to your item yourself. As soon as you apply a recipe, the associated currency gets transferred to the seller. If for some reason the trade gets cancelled or you click away from the bench, the respective items and currency goes back in the inventory. This way we have a safe and convenient method of trading. Also these recipes can be listed officially on poe trade.

Looking forward to hearing from you.
