Comment 6 for bug 1919929

Not sure why you think it's not a charm issue? Look at the work done in the Kubernetes charms around snap cohorts for an obvious and trivial counter-example? Landscape deals with machine primitives. It has no concept of what those machines are running. Juju does (and so correspondinglty) do charms. It's easy to see how you could within the charm to ensure that there is consistency within an application. I don't see how you could do that within Landscape... unless something like the charm pushed a bunch of information to Landscape.
