It seems like they just want a semi-custodial, intermediate hop where there is an always on server to prevent force closures because a mobile node is offline.

I personally think this is clearly a problem that needs to be solved by the LSPs themselves (within their nodes, not apps). Zeus did a great job of this, but in doing so they exposed problems with other lightning models. I hope that they can come together with Mutiny and find a solution where their nodes incorporate these types of payments as part of their business model. Aggressive Nostr posts and removing the ability to send certain transactions is not constructive.
