Keep digging. How long does the large amount of liquidity have to stay locked up? Iirc, it’s cumulative and massive compared to LN nodes. Even big ones.

It's 4 weeks I think, the user should redeem the txs in this time frame, I think it's because of that, so that liquidity isn't cumulative. But I'm not an expert neither in LN. We can only tell when there is a working wallet. But imo LN just as a user is a pain, but it's still the best we've got.
