Your use of "whatever" proves my point. You might be comfortable accepting such a poor term, but I am not. If I were the member of a family with a grandparent whose identity is questionable, but my own parentage is not (and we have the DNA to prove it), suggesting that my parents might not have produced me or my siblings with Uncertain Family category is a far cry from not being certain about my grandparents. WikiTree is already stupidly difficult to use without additionally being simply stupid.
