FWIW  I did recall seeing a simular request. So I went to the archive
and found http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2019q3/013299.html
Quoting that email with Subject: "Split DNS and DHCP listeners on a
single interface with iproute2 and systemd-networkd"
} My ultimate goal is to have a single instance of dnsmasq
