Well, from my POV the binkd behavior looks logical here. If you specified the values of the @me array, then only the AKA specified in that array would be presented. Since you did not specify any values in @me, binkd presented all of your AKAs during the handshake. In after_handshake() hook, you see the AKAs that were presented during the handshake.

"Perl on_handshake(): @me contains no valid addresses" is here rather not an error message but a warning.
