There is no status quo to rebuild.
Loss of trust, loss of momentum, loss of context, loss of relationships - insofar as any of these things existed, they are permanently destroyed. That's what will need rebuilding. The original process took decades, if not a century or more. You can't just disrupt that and then expect to restore it easily - or expect it to spontaneously reconfigure on its own with reliably desirable outcomes.
People working in the government are not fungible labor units like GPUs or VMs, to be spun up and disposed of without consequence. The network formed between people is even more important than the individual jobs - and it has an insane cold-start penalty.
Maybe if the folks in charge were absolute geniuses in leadership and organizational psychology, something miraculous might happen. But, that's never a thing to expect in general, let alone given the evidence at hand. They're making the classic blunder of trying to rewrite the system from scratch, which has almost never gone well for anyone.
