I bought the ewoks line and several of them are like that with just the card behind the bubble. I never opened them and don't intend to. I eventually plan on trying to trade them for equally loose counterparts as I am sure someone may enjoy them sealed away. That said I have no qualms against someone who wants to u grade something in that condition. The first figure you show though still has a good deal of cardback and though in lower condition this I would for sure be against u grading. Basically if there is enough card left someone might enjoy seeing the art, pics, etc. then I wouldn't u grade. If all that is left is the bubble, unless it is an extremely rare card type or something (saw a ledy figure in bubble like this one time) then what good is the card and bubble doing at that point?
