The router is running OpenWRT, I could make that change manually but
then I wouldn't be able to fully manage it with the GUI any more.

Can you confirm if this is the only way it can work according to the DNS
spec, or is it a dnsmasq design decision?

Could a software approach be taken by default, waiting to see if any
resolver provides a positive response before sending back REFUSED to the
client?
