except CJs and Monero are more battle tested and already resilient. so barring extreme technical breakthroughs we have reasonable certainty they will continue to provide privacy.

which is NOT true of LN, where privacy guarantees are difficult to quantify, dependent on use-cases and poorly understood.

there isn't a whole hell of a lot anyone can do about a diffie-helman exchange ya know? its been around a while. 

 I’d say that CJ is part of LN privacy, as something that should always be done prior to using UTXOs for LN nodes.
