Yes, this is an issue, and you could equally have done this over cable modem.
Or if you plugged a layer-2 ethernet/802.11 extender in to a wired port of
your router, and your neighbour did the same thing. It's always possible
to defeat things; the question is whether or not your 1% situation should
mean that we have no security for 99% of the other times it works fine?
That's why I suggest that the wire permits a TOFU bootstrap, not that
it's forever insecure. I don't see how your buttons, etc. would have
permitted anything, since that would have been about the wifi.
My understanding is that a new generation of powerline ethernet now
actually uses 15.4 MACs with a different PHY, and in fact runs Zigbee over
it, for exactly the situation you mentioned.
