The art use case is a nice one I haven't considered. But that sounds like something that's easy to cover either in the definition of public spaces or a flat out exception like there no doubt will be for research.
I fully concur w.r.t. applying the same restrictions to European governments, i.e. this sentence from the article: "These include the German government is planning to roll out facial recognition technology [...] after a successful trial in Berlin." The "successful" trial published an anonymized evaluation, results were horrid. It's quite amazing how split the political field must be here. In Germany that's also down to law enforcement exemptions from quite a few privacy laws, no "national security" pretense needed.
