I do like that it's technically possible to do cross chain LN payments and routing between liquid and bitcoin. Unfortunately though, liquid continues to disappoint in terms of user-level adoption. It would have to feature both bitcoin and liquid support and building that out for very little use might be a big time sucker. Though from a privacy perspective, confidential transactions are nice. But that's a big lift that I would also have to push adoption for Liquid too and that's not a hill I think I want to die on.
