Many of us think that Efail is orthogonal to this problem and consequently while it’s a real issue, as a rationale, it’s lacking.

You might disagree with us, and I respect that. Nonetheless, I find Efail to be unconvincing. I’d love to debate this further, but do you have *another* rationale, or it only Efail?
