It seems @ACINQ is now leading a lot of these bleeding edge capabilities - splicing, trampoline routing, BOLT12, etc. In the meanwhile lnd focuses on shitcoin factory :/

I wish that we would have Phoenix experience, but it would somehow allow migrating the channels to another LSP super easily when things go wrong with ACINQ (and without any need for ACINQ interaction) and relatedly it would also allow using different nodes for trampoline routing.
