Comment 12 for bug 1942289

> If you need to know about counterpart units, that is what a peer relation is for. If you want to know if your unit is going away that is $JUJU_DEPARTING_UNIT, IIRC.

Has the behaviour in juju changed at all since earlier versions? e.g. around departing units and leadership. It's just keystone has been around for a long time, and it's curious that this bug has surfaced. Certainly, it has a bug, but I'm wondering if leadership was dropped on the departing unit unless it was the last one, previously?
