Agreeing with main points in 3, 4, 6, 10 in More objections to 2, 5, 7, 9. Most important dispute is regarding risk management, 1+8. Recent advances in torsion-point attacks have killed a huge part of the SIKE parameter space, far worse than MOV vs ECDLP.

The "failure" comments inside 9 are a smaller-scale risk-management issue. Here the paper is correct in saying that decryption failures increase the post-quantum attack surface, but is wrong in claiming that SIKE is the only #NISTPQC encryption option without decryption failures.
