TL;DR: Unless the falsity propositional constant is part of the defeasible assumptions, the grounded and the well-founded semantics for ABFs lack most of the desirable properties they have in abstract argumentation frameworks (AAFs), and for simple definitions of the contrariness operator and the attacks relations, preferred and stable semantics are reduced to naive semantics.

Abstract: Simple contrapositive assumption-based frameworks are a general setting for structured argumentation, providing a robust approach to reasoning with arguments and counter-arguments. In this paper we extend these frameworks with priorities and introduce some new results concerning the semantics of the resulting formalisms.
