This argument is not nonsense for administrators using djbdns and
other software packages from the same author. Dan designes his software
packages to be minimal, fast, and secure which allows him to keep them
stable for a long time. Qmail, for example, did not change for multiple
years. For this reason, many users of Dan's packages prefer them because
they remain secure and stable for a long time. Running Qmail and djbdns
means that you do not have to look for new security holes and you can
keep them running unchanged for many years.

This advantage is destroyed once protocols are changed in an incompatible
way.
