Dnsmasq probably fits their requirements more closely than BIND or
Unbound, but it's still a server that you have to talk to via a stub
resolver.  In other words, there's still the "last centimeter" of DNSSEC
to secure :-)

I’m highly supportive of the idea of writing a new validating stub .. but I think it’s folly to link it into the boot/cron system.  Same feeling I have with systemd’s integration into /tmp clearing, and a host of other things it shouldn’t be doing directly, or possibly at all.

Other than being part of the same umbrella project, being developed by
the same people, and sharing some utility code (config file parsing,
abstract data type implementations, etc.), I'm not sure if it's accurate
to say that it's linked to the boot/cron system, at least not in the
runtime sense.  It certainly doesn't run inside the PID 1 systemd

Is the situation really that different from, say, 4.x BSD?  Your init
system, startup scripts, cron daemon, etc. and DNS stub resolver all
came from the same vendor and were integrated into the base OS ;-)
