Note that there is a difference between the number of TLDs and the rate by which they are added. In many discussions I have been involved in, it is the rate that scares more than a number. We know running a zone with "lots of entries" is not such a big problem. We know how to do that. Also sort of how to handle high rate of changes to such a zone.

But, for the root zone, going too fast from "small, with small number of changes per time unit" to "a large zones with large number of changes", is a move that scares at least me. Specifically after looking into the issues quite a bit. It scares me a lot more than the end game. The root zone is used in many many ways today that is built upon the assumption it is small and do not change often.
