yeah, i read Human Action twice lol... does not need more features, just needs more routing algorithms, IMO... right now we have simple straight routes, we have keysend and AMP, it's lightning, where is the fan-out-fan-in multipath redundant routing!!!!???
to me, after examining all the info about the protocol that seemed like the direction that would be most important to explore, how to do redundant paths, and the other part, improving network state data propagataion, because the other problem is congestion - clients pick routes randomly from what they know was last known to be operational, but this whole thing of hiding channel state is a real problem, there needs to be some way to reveal enough channel state to help nodes making invoices avoid currently congested paths, this is almost the main problem, nodes being offline or unreachable is less of a problem than nodes getting too much traffic in one direction at the same time that they can't route
