// Mesh Delivery Failure is currently turned off for blocks
// This is on purpose as
// - the traffic is very low for meaningful distribution of incoming edges.
// - the reaction time needs to be very slow -- in the order of 10 min at least
// so we might as well let opportunistic grafting repair the mesh on its own
// pace.
// - the network is too small, so large asymmetries can be expected between mesh
// edges.
// We should revisit this once the network grows.
