Connecting to a cluster with just a single coordinator address

We've made some changes in recent versions of FDB to allow clients to connect to a database by going through a single coordinator. We still require that clients have all of the coordinator IPs and the latest generation IDs in the cluster file. I think it would make things easier on clients if they could connect with just the database name and a coordinator DNS names. That would allow us to store the coordinator addresses under a single DNS name, and remove the need to send cluster file updates to clients when the coordinators change. Is this a viable strategy?

Start by reviewing the recent FoundationDB changes that let clients connect through a single coordinator, then examine the cluster file's coordinator IPs and generation IDs. Determine whether a database name plus coordinator DNS name is a viable client connection strategy; the issue provides no file or test entry point, so completion would require a documented design decision.
