I think the bread/can/rock stuff were part of the "things which are already in game" - which, though they don't do much, aren't adding anything new in terms of content, and as they could be held in hand, need to be able to visible in hand for consistency.
Adding a bow would need an extra animation adding to it - though a crossbow could possibly work with existing pistol / rifle animations. Anyway, maybe not much use for 2238, but I'd definitely see potential for other mods wanting such weapons, post 3D era.
