Andreas, I am not a nice guy. I am only lazy. If the change to exim4 (it now displays a debconf note to everybody who tries do dpkg-reconfigure exim4, -base or a daemon package telling them to dpkg-reconfigure exim4-config) saves #debian from answering the question "how do I reconfigure exim4, dpkg-reconfigure exim4 does nothing!" twice a day, it is a good change.
I basically agree with you that people who not read the minimum basics of documentation are a nuisance, but they're unfortunately real. You need to hurl the docs into their faces. And even then they're going to ignore them and google for answers instead. And on google, they're going to find wrong or outdated docs.
