But I’m not sure that a long list of closed channels is a turn off to users who just want their payments routed successfully. Users are generally self-seeking just like node operators, and I think they will generally pick whatever node is most likely to route their payment - factoring routing fees of course - the same way that a node operator will generally act in whatever way gets them the most routing fees. For a lightning user who is planning a path for their payment, if that means picking between a node that aggressively closes unnecessary channels to provide an excellent routing experience, or a passive-aggressive node that quietly blacklists channels without telling their counterparty (or any users who might route through that channel), I think the self-interest of lightning users will generally guide them to the former.
