Isn't it a big difference? That's a difference. But testing lexical variables for whether they are bound is a rare use case (is it one at all?). I mean, when you are interested in the binding of a variable that might not be bound (defined), that variable will typically be special, or not bound at all, i.e., not lexically bound in any case.
