I was just learning about Liquid as a way of rebalancing lighting and having a hard time squaring the cost/benefit. If you want to move liquidity out by swapping via boltz to liquid, there's a network fee of 428 sats + 0.25% (+ whatever routing fee or channel opening fee gets you to the Boltz channel). Then you have L-BTC that you hope to swap back to on-chain bitcoin later, but will have to pay whatever the BTC on-chain network fee is + 0.5% for the Boltz fee... seems like it's a paid hedge to assume that BTC on-chain will be cheaper later, but you also get stuck with your BTC as L-BTC so you can't just use it to open a new channel until the fees go down...

Maybe I'm missing something but it seems like a lot of extra work and side-storage wonkiness that could end up being more costly ultimately as a way of creating inbound liquidity...
