Very good point.
Two possible responses come to mind.
1. Cross-asset brokers charge a standard option premium to perform the brokerage. I can't tell if you think this is totally broken or if it's just sad. I don't understand lightning well enough to figure that out on my own - could you expand more on what effects this would have?
2. Cross-asset brokers require counterparties to issue them a symmetric but slightly more out-of-the-money call, which they can redeem in the event of a large FX swing. This bounds their FX losses.

I agree. Negative shadow prices are incredibly important for optimality of constrained network markets where flows in opposite directions cancel (as is the case with lightning). See for example FTRs. It’s unclear to me how well the analogy holds, but it’s worth considering.

But regardless I suggest the protocol should support negative fees, even if an individual routing implementation prefers to treat as 0 for simplicity. That should be up to the implementation I think, and not a protocol constraint.
