This is for the usecase of running MASQ Core Serving-Node on an VPS, where you don't want to proxy any traffic from the local machine or local network through MASQ Core.

When the MASQ Core DNS resolver on 127.0.0.1:53 could be switched off completely..

..i could easily run stubby or similar software as a DNS resolver on standard DNS port.

..i would not have to worry that my VPS is routing traffic unintentionally through the MASQ Core Node.

what i initially wanted to do, is running stubby as a DNS resolver that is encrypting DNS queries via DNS over TLS. that way i could set the DNS server setting of MASQ Core to 127.0.0.1 and route all DNS queries TLS encrypted to Quad9 for example. I know you can use a different port than 53 with stubby, but you can't configure MASQ Core or /etc/resolv.conf with that port. So it would have to be 53 always or a redirect of that port and i think it would be easier if i could just switch of the internal MASQ Core resolver.

what do you think?
