Its can break open the whole LN privacy though. Also works both ways. If through timing analysis your LN channel is identified to you, then the UTXO is and thus all previous cospend will break that on-chain anonymity. Its superior privacy to purely on-chain since it requires this network attack but still presents a massive attack vector compared to a Monero with both on-chain sender, recieved and amount privacy AND network level privacy through Dandelion++ IK I'm preaching to the choir on the Monero point with you as you're aware of those technologies, I'm just bringing it back to Clippy's original claim that lightning privacy makes Monero irrelevant.
