But accurate and timely maintenance of a local root server seems to me
to be a nontrivial task, especially if ISP sysadmin workloads have not
changed since I knew many personally -- and I suspect that if they have
changed, they have done so for the worse.

While I don't see any huge great need for this (dnscache starts up with
better performance than I could have believed when I was a BIND user), I
cannot see any big issues with this (and I do agree with most of your
other objections to the posted patches -- much better done with
pre-and-post processors than mangling djbdns code IMHO).
