It sounds like it was dropped due to difficulty in the routing protocol. Is that difficulty documented somewhere I can review? If so, I might take a crack at a solution to it. 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.
