I can't really see that it improves on anything, isn't it the same as saving the GAM file to be able to review previous turns.
It doesn't really enable you to save the simultaneous game turn you are playing, quit the game and restart and continue on the current turn where you left off, right?
So as to PBW and cheating, can't see any issue there.
EDIT: Darn that Geo, beat me to it again.
