The page you linked to was last updated 11+ years ago. Notice the discussion of qmail|ucspi|djbdns-installer packages? They are not around anymore, you can install qmail/ucspi/daemontools etc. There is even djbdns and the debian tweaked + community patches version known as dbndns. Yes djb and debian devs are quite opinionated, but I do not think that is the reason that publicfile is not in debian despite the fact that so many other djb packages are. I think the reason is low demand largely due to the fact that gnome-desktop depends on gnome-user-share (AKA: apache).
