I note that draft-arkko-arch-infrastructure-centralisation made some helpful observations regarding the dangers of centralisation, with specific points relating to DNS. It included the following points in the recommendation section: "Where such centralised points are created, they will eventually fail, or they will be misused through surveillance or legal actions regardless of the best efforts of the Internet community. The best defense to data leak is to avoid creating that data store to begin with". This seems to be good advice to me. Andrew
