Is jwilder/nginx-proxy still actual since embedded DNS server in user-defined networks was introduced?

As far as I can see before user-defined networks feature was introduced by docker restarting a container A linked via --link to the container B had required restarting the last one too due to changing A‘s IP address. And because of that projects like docker-gen and nginx-proxy appeared.

However, now exists an Embedded DNS server in user-defined networks. Does it mean that one can configure nginx <-> upstream communication using modern docker approaches and without 3rd party tools like nginx-proxy?
