In 2f4d8e577ca7bc51fb054b8c2c8dd57c2e188a41 I argued that following CNAMEs in the stub is not necessary anymore. However, I think it' better to revert to the status quo ante and follow it after all, given it is easy for us and makes sure our D-Bus/varlink replies are more similar to our DNS stub replies that way, and we save clients potential roundtrips. Hence, whenever we hit a CNAME/DNAME redirect, let's restart the query like we do for the D-Bus/Varlink case, and collect replies as we go.
