Erm, okay, D & N.
It appears that the only folks who will be ruined by this are the (already pretty well-known) wise-guys who have been dodging US taxes for their whole career here.
Those who have been abiding by the IRS code and submitting W-4s, have nothing to worry about.
Unless, of course, they have been so **** with their finances, that this 1-year minor interruption to their cash-flow will wreak havoc.
Enjoy the 'freedom', you're paying for it.
