I think that's a deficiency in modal logic insofar as it's supposed to formalize good informal reasoning. But I can see why it's done; it's difficult if not impossible to give formal definition of "justified". Yes.See my answer to brent. The whole AUDA is made possible because we do have an excellent axiomatisation of justification.
It's an excellent axiomatization that relies on inference from axioms. To say it formalizes good reasoning would mean that I would have to axiomatize vision before I could see anything.
