To be clear: I’m not saying I’m absolutely against the 1ms precision in attributable failures. I’m only highlighting that I want to have a better understanding of the privacy risks before making a decision, and how important random delays are for privacy at different stages of the payment path, to ensure that attributable data doesn’t incentivize in the wrong direction.
I do think that a 1ms precision isn’t at all important for payment UX, and 100ms precision per-hop would be enough.
