I don't see from where you take the right to decide for a TLD registry how they should run their operations.
The same place they find the right to take up space in my routing table.
Apart from that, I can tell you that these shorter RTTs make a hell of a difference.
Then you're running the wrong DNS software. A good resolving server should keep track of the TTLs towards different nameservers for a zone and try to talk to the one with the lowest TTL first most of the time. From your other message:
There is, however, a difference between routing table pollution (mostly because of missing or failing aggregation) and small prefixes in the routing table due to "special" PI service blocks. One should not mix this.
It's natural to look at these differently, but the end result is invariably the same: more CPU and memory usage in the routers.
