I would be against official recognition.
Not because they don't deserve it for showing respect BUT because of the fawning culture that you would get as a result where towns and villages who decide to do one thing would then demand the same recognition as people who had done something out of the good ness of their hearts.
Politicians and other would jump on the bandwagon.
Better to be held in the hearts of people in thanks for the continual showing of respect that it becoming a "must do" because some politicians have done it and a place has received an award. Better to keep it private than it become a tourist thing.
