Whilst PPRUNE is powerful, I think it might have more to do with Alan B getting knobbled every time he entered the Ops Room by NOR controllers dragging him over to the radar and asking him how we were supposed to keep the 5 Eastbound tracks converging on Kippa 4 miles apart from each other.
Apparently the ADNC people got all shirty as well when someone went 1 mile off route trying to keep vertically separated aircraft in the UIR 4 miles laterally apart!
As I said before, another example a knee-jerk, ill-considered, quick-fix reaction from Ops to which we have become accustomed.
