Maybe a safer bet might be to leave resolved off during upgrades on the server edition? I don't think we can reliably determine whether people have deployed things in a way that relies on /etc/resolv.conf only listing a fully blown DNS server or who are fine with it being a more restricted stub like systemd-resolved. I'd claim it's reasonably safe to declare that on workstations having a restrictive stub between local clients and a real DNS server is OK, but maybe for servers we don't want to make such a claim, dunno, and just enable this for newly deployed stuff but not on upgraded stuff.
