I have a couple of questions about the things DR critters drop.

Why do things like embroidery needles, cracked mirrors, wooden hairbrushes, grimy bars of soap etc. stay in the room and not go directly to the junk pile?

Why are items dropped by critters that stay in the room (even if we use loot goods) and disappear if we try to pick them up?

It seems to me that these things just cause a lot of clutter in a room and that can't be good for the speed of the game?
