I don't know why this necessitates the removal of supernodes though, because it has always been the case that desktop clients could disable supernode functionality with a checkbox option. Why would it ever be enabled (or even an option) on a mobile client? Or is the issue simply that the majority of clients have become non-supernode-capable and it became an issue? I wish he would have went into more detail on this because at first glance the explanation is not sufficient to justify the change.
