I'm rather sure that LN Symmetry/eltoo needs either APO from BIP-118 for the backups to become simpler, or as said in the update on delving, some combination of CSFS with a covenant opcode, like CTV. I think that everything else for eltoo is in, except any of the needed supported protocol extensions? (Don't take my word on this, I may have missed something.)

Maybe it's time to point those datacenters full of miners you bought at the LNHANCE activation client 😘🤓
