Interesting paper – thanks for giving the list a heads up. My comments:
1 – I think the claim “First, removing resolvers simplifies the overall system” is a matter of opinion. I may even argue the opposite, that the prevalence of large scale resolvers simplifies the overall system (but as an operator of one, I am admittedly biased).
2 – The sample size of a resolver serving 100 home users seems small. You may want to try to collect data from larger networks.
3 – I am not sure that authoritative server operators would be prepared for the large increase in query volumes, and not sure they’d be prepared to mitigate that by compromising with longer TTLs.
