Indeed, but extremely annoying. If RD 743 gets rescinded I'll be hit with and 800k Tax bill, not enough to justify 185 days a year away from the family, but an almost impossible amount of savings to achieve while keeping everyone happy and cheerful. Practically less holidays, less western food, no more extensions on the house, only value saving maintenance, keep aging cars, etc.
On the bright side I managed to extend my tax free life by another decade, which I didn't expect when I came here. And IMHO I most [pragmatic] people here will follow the same approach, once settled it becomes near impossible to find a better deal elsewhere, even after tax.
