Live experiment is easy

If you have the capability to run a few VMs you could do the experiment yourself right now.

All DNS servers have a cache file they start up with that tells them where the 13 root servers are. So you set up an experimental DNS server that has changed those IPs to point somewhere else, i.e. some VMs you've set up as root name servers that use a modified copy of the root zone file. Then you point clients at your experimental DNS server and they see the world via the modified root zone file. If it is missing .ru, then no .ru names will be resolved by your experimental DNS server but it will perform recursion for anything else. If there was a .porn TLD where all porn was kept, it would be easy for countries that want to make a porn-free environment to use a root zone file that excludes the .porn TLD.
