Thanks. I did not fully understand the proposal, but could be useful in some scenarios. Inbound liquidity will always be an issue in lightning. However once enough channels are open, the issue will affect less.

IMHO L1 funds are always kept with the keys, and only in the mining process those funds are subject to some risk (near 0 of course) of been taken in an attack (51%, Double spend, etc). Additional consensus instances that will put ownership in the limbo (like liquid or this one) is something I would not like to experiment with.
