Hi Peter,
Yes, idle is idle, and it is what it is. Boys will be boys. The explanation I heard before was the vacuum generated by deceleration with the throttle closed and its effect on oil pulled past the rings and valve stems was a result of the fuel economy inspired injector cut LH2.4 does on throttle down from speed. Does this make sense? The idle valve opens to keep down the blowby until the speed returns to match the pedal position. Downhill, yes!
