Agree, specially with the "mass adoption test", good insight, will try that myself.

Phoenix is hands down the best in class for self custodial LN wallets, its simplicity is what is needed for mass adoption, geeks wallets are good for testing, nothing more, non technical people will just scare away

Zeus, which in its web site defines itself as "an open-source, self-custodial Bitcoin wallet that gives you full control over how you make payments." is for geeks, I played extensively with it, but will never recommend it to anyone that is not technical.

BOLT12 is definitely a step in the right direction, no web server and onion messages for end-to-end-encrypted connections between nodes, hopefully the adoption will speed up.
