Comment on "Why interference phenomena do not capture the essence of quantum theory" by Catani et al

It was recently argued by Catani et al that it is possible to reproduce the phenomenology of the double-slit experiment with a deterministic, local, and classical model (arXiv:2111.13727). The stated aim of their argument is to falsify the claim made by Feynman (in his third book of Lectures on Physics) that the double-slit experiment is ``impossible, absolutely impossible, to explain in any classical way'' and that it ``contains the only mystery'' of quantum mechanics. We here want to point out some problems with their argument, and defend Feynman's position. This is an update of our criticism following an update of Catani et al's paper that clarified some issues we had previously raised.
