This is gonna conflict a bit with docker, and other  users of network
namespaces, like systemd-nspawn. When docker runs, it picks up the
current /etc/resolv.conf and puts it in the container, but the container
itself runs in a network namespace, so it gets its own loopback device.
This will mean 127.0.0.1:53 points to the container itself, not the
host, so dns resolving in the container will not work.

Good point; would it be fair to treat this as a blocker?

(This also assumes that the docker containers will use the same security policy as the host; i.e. that they will be administered by the same entity, no "docker hosting" businesses.)
