We already have the proof of use-case, imo. It’s custodial Lightning. Wallet of Satoshi could offer the exact same service with just a CTV pool in the most naive sense. And then if WOS ever vanished, literally everyone could redeem their coins still.

All we need to prove this viable is demand for people to use custodial wallets and assume they don’t want to be rug pulled.

Also, I’m not trying to make a sense of urgency here, just to explain. I don’t even think there is a rush, I just think CTV is basically just waiting for there to be a clear line in the sand for people to decide about.
