Why should it?

That's not true. Try for example:
dpkg-reconfigure xserver-xorg

Or even better, try:

echo 'postfix postfix/root_address    string  snork' |
  debconf-set-selections
dpkg-reconfigure -fnoninteractive postfix

You'll see the postfix config file getting changed (and mind you, root
mail is redirected to a probably non-existing user named "snork", so
don't try this at home)

That's the behaviour I expect from dhcp3-server as well, instead of
ignoring debconf-settings alltogether and making up its own mind.

Well, I think you did understand what I mean, but your answer doesn't
convince me yet, as there are two major packages that behave differently.
