I never quite understood why we can`t place metal objects in a smelter and get back a bar per slot of the object, or dismantle liftable things that have metal components for some scrap metal that can then be used with an alloying crucible to obtain bars of metal. This way we could actually turn swords into plowshares, or the opposite.
I`m similarly puzzled by not being able to use liftable wooden objects (like chairs and such) to fuel at least bonfires nor burn non liftable wooden items (like cheese trays) in a kiln to produce charcoal. Also it`s a bit strange that no liftable wooden object leaves behind splintered wood that could be used as fuel upon destruction.
There might be some issues regarding how to handle quality formulas on those items, but the general idea of reutilizing the materials seems like a logical next step considering existing game mechanics, so I leave it here as a suggestion.
