First question is did it actually happen?
Given that 05L/23R is the bit of tarmac you actually taxi along, I would find it at least a bit odd to then turn around at the end of the taxiway expecting to take off.
It is likely that some day some one will do it or try to do it, especially from the 05 end. Why does it have to be made so difficult for the occasional visitor? White pages, yellow pages, ramp control, ground control, FMS arrivals, but only for the initiates etc. etc.
