I believe organisations will continue to want to use split
DNS. Running split DNS will become much more than just
runing nameservers and telling the clients where they are.
It also involves reconfiguring routers to filter routes.

I did read the draft. You draft is forcing the use of
anycast to get load sharing. The other proposals don't
have this property. You can get load sharing w/o
resorting to unicast.

It's not a requirement if the ONLY thing you want clients
to know about the DNS is the addresses of nameservers. In
the real world there are lots of organisations that want
to push other configuration details out. The proposals
you are competing with can support this.
There have been cases where I have wanted to push out the
other DNS configuration and times when I don't. The lack
of support for this is reason enough to reject this solution.
You draft also states that the anycast addresses will have
global scope. Does this mean that we are going to have to
introduce the concept of stub routers so that the correct
prefixes are configured for nodes on a routerless network?
