I don't think it should... the way I see kingdom items is that "KingdomA Item" is made in "KingdomA"... kind of like today where we have all this non-sense stuff where nothing is Made in USA anymore... It doesn't matter who holds it, it can be used... It honestly doesn't make any sense unless it's some crazy weapon with 3 handles and blades pointing in 5 directions that can only be weilded by the Ninja Hippies of the Underground Cult.
Maybe items important to a Kingdom should be made tag-locked (ex. Zormite shield of Honor)... but ordinary things like shields(Dustari, Zormite, Forest, Kurenai, Pirate shields) shouldn't be locked.
