Review for NeurIPS paper: Decentralized Accelerated Proximal Gradient Descent

Additional Feedback: edit I have read the rebuttal, and I would have liked the authors to point out precisely *what* technical points change and are difficult to handle. I think it would be great to actually highlight them in a revision of the paper. On a side note, I still believe that it is possible to get rid of the consensus step on y_t, and closeness between y_t and \bar{y}_t should be enforceable by the consensus step on x_t. This should be better in practice, since the consensus steps that are currently performed on y_t would also benefit x_t. A comparison with higher values of K would also have been welcome.
