So an increased CLTV delta could avoid this? LND has by default 40 CLN has 34 Eclair 144 Those numbers means number of blocks until a HTLC can expire (if I remember correctly). So would be indicated that peers should have same CLTV on both sides, even if they use different LN implementations? Why each implementation have its own default CLTV? Why we can't have something unique general for all? Are we going to be like with the mobile chargers connectors?
