The third sentence means it is standard practice to validate from only a single network perspective today. I have heard we would not be the first CA to do multi-perspective validation, but as far as I know we would be the only CA of significant size doing it. I do not know of other CAs doing it today, but we have not done an exhaustive survey. Also, architecture and implementation details matter for this kind of feature. How many perspectives, what networks... We are lucky to be working with a great group from Princeton that has been helping us design our implementation.
