I have been struggling the last hours with the same exact issue trying
to add replication to memcached.

The problem is that there is no a point on which i can identify
what's the exact departing unit?

And this leads to manual operator intervention, which is _highly_ non
desirable for a juju deployed environment.

+1 for having this feature implemented.
