Breaking a furnace, blast furnace or smoker will drop its stored xp

I think breaking a furnace, blast furnace or smoker and having it drop its stored xp would be a good idea mostly for automated designs. Otherwise a way to extract that xp, besides turning off the automation and smelting another item, would be nice. It just seems clunky that now that they store xp there should be an easy way to extract that xp.
