I think it would depend on if the quilt was to be a gift, or just a utility quilt to be used at home. I would also have to decide how difficult it would be to fix the problem. Just how noticable the oops is also plays into how bad I would want to fix it. The minor things that most non-quilting people never see (or know what they are looking at) I wouldn't fix. If it just glared at you, then I would want to know so I could at least attempt a repair.
