Item Dropper?

To preface, I haven't played this game yet, just watched a guy (Aavak) play it and I have a thought on something I would like to have when I finally get around to playing.

Aavak had a shop front that was stocked via catapults from the second floor, and he was having a bit of trouble getting them to hit their targets while not hitting anything else. So I had the thought of a Dropper (mechanism? Item? Part?) that would stick through a floor and drop items. Have it function kinda like a mix of the wall pipe and a catapult, so it can intersect with certain items (floors, maybe tables and/or shelves) and send items to a target like a catapult (but basically only straight down.) Maybe have roof mounted cannons later on, once you get steel.

Anyone else want and/or hate this?
