That's a reasonable question, and one I've asked myself in the past. The
answer is no, although I can't help thinking that's mostly because the
10 BIND (or BIND-a-like) servers override the value from the root zone
file with that from the root-servers.net zone file. However, making the
values consistent is insurance against a possible operational problem
down the road (including, but not limited to signing of the
root-servers.net zone).

Meanwhile, at _best_ the current situation looks like an oversight, and
one doesn't have to poke very hard to apply adjectives like "silly" and
"amateurish," neither of which do a lot to instill confidence in the
current layer 8/9 environment.
