The authors' feedback resolved some of the concerns raised by the reviewers. Unfortunately, we have not been able to reach a consensus, so this paper is borderline. On the positive side, the paper introduces a new and interesting MARL framework and provides both theoretical and practical contributions. On the negative side, the authors should better highlight from the beginning what is already present in the state of the art and where their contributions start from, and they should provide a more extensive and accurate empirical evaluation. The requested changes are quite significant, but given the authors' rebuttal, I feel they can fix these issues and so I suggest acceptance.
