I can see your point and the military have previous in this regard. RRP (Flying) used to be called flying pay. When you PVR'd you kept it. The change in nomenclature to RRP went mostly unnoticed until a couple of years later when they announced that when you PVR you will lose a large chunk of your RRP since you are no longer being retained.
They are devious gits and nothing is done without reason.
I hope you're wrong though.
