Pub/sub events for registrations

Is it in any way possible to "subscribe" to a Swarm registered process? Similar to Gprocs [gproc_monitor:subscribe](https://github.com/uwiger/gproc/blob/master/doc/gproc_monitor.md).

I want a process to be notified when a name becomes registered / unregistered (crash or shutdown). I can do this by looking up the Swarm name and then using `Process.monitor` on the PID, and keeping track of pid <-> name relation until it crashes, but that's a lot extra (and fragile) work.

Are there any plans of adding such a feature?
