I really have some doubts about this new way to look at this legal regime.
The problem seems that in a book who is about to sell in so many countries we may have many ways to look at these issues and at this regime.
In Portugal there was an issue also with someone a few years ago and the guy won the court case and the photographer had some problems to achieve a good deal.
As a consequence of that, the European highest Court made a decision that forbides the police to take a picture of people driving, for speeding tickets, in a way that they can be identified. Portugal followed this and pics for speeding tickets body of proof are always made from behind the car.
From my experience, it´s always in the beginning of a new legal regime that huge and not nice surprises can happen just because people (judges) don´t have an understanding beetween them about how to aply the law. And in the other hand the highest courts also don´t have many decisions. So this first times of the new law is always the most "dangerous" period.
As I said above, the best way to deal with it is to go with maximum caution and in my case, like I said, this means that i will try the most i can not to shoot people in a way that they can be identified. I will try to shoot people from the back and when from the front, I will try to edit / process in a way that they can not be identified.
Caution would be the best "adviser", for now.
