With Powers no longer being restricted to the same sort of contiguous "blob" territories as in the original Powerplay and a lot more interleaving being possible, the old map wouldn't have worked. It only included the approximate inner half [1] of the bubble, even in the original Powerplay, because the Powers stayed away from the fringes.
With Colonisation it'd be even less accurate for showing the real borders - here's a rough map of the bubble and its growing fringes, looking from behind towards Sag A* - white dots are original systems, yellow are successful colonisations, red are ones where the first station is still in progress ... and Powerplay is still largely stuck inside the middle of the white area so you wouldn't see any of this on the old map even if it still worked.
