The ones they do mention are all imperative languages with added deductive verification in a Hoare calculus style (think loop invariants). The ones you mention are functional languages with a different style of proof (think inductive proofs).

Of course there are overlaps between the two styles (notably in Why3), but there are pronounced differences between them.

Ok. But that's not what I was getting at.
