I think > those are two different cases. The thing that is similar is that people set rp_filter inappropriately (no end host should have that knob enabled, ever, it's totally unnecesary). And the risk here is similar, distribution X will set it so Y will say "we probably should set it too even though we really don't understand it fully".
