Multiple DNS caches exist on Unix(like) systems, but only few have decent system integration. systemd-resolved has a good integration, but poor DNS protocol implementation. Advanced DNS resolvers have many good features, but each has different configuration syntax even for basic settings like forwarding.

We think missing integration can be provided by dnsconfd daemon, which would provide glue between Network Manager and resolver running on localhost. Would provide unified DBus and command line interface for different cache implementations.
