Mandating face coverings for everyone who leaves their house is a large-scale change. No, I am not American. I'm also now not really European, so that should tell you where I am ;)

Edit: I decided to clarify why I think it is a large-scale change. I cannot think of any other action we are actively obliged to do by law, except for possibly covering gentials, when leaving our own house/property. Introducing any such obligitory action is, in my opinion, a large-scale change in mandated behaviour.
