"In the 1/20000 times this becomes an extended outage, it would be easy to
narrow down - one could logically disconnect the known behaving CPE's from
the network, providing a  list of physical splitter ports to go and
disconnect. There's a big if about record-keeping for splitter ports here,
but it's not technically impossible."

You would need to do a physical one-by-one serial disconnect of every port
on the PON span whether there it is an active port or not (including never
connected) because anyone can simply plug into any port on that PON span.
There is some logic you can apply to help order of disconnection during
trouble shooting to minimise disruption if you have good logs and even
better if you control ONU, a point that's probably not lost on NBN Co.
