The announcements are all coming at once, but decisions like these take a long long LONG time to percolate through the federal bureaucracy. Not quite 8 years, but I would expect they've had contingencies for going down this road kicking around for at least a year or so. I don't think they're just impulsively scrambling to fulfill all their whims, they're just striking now while they have the political capital and the opposition is too distracted and demoralized to make a fuss.
