https://github.com/juju/juju/pull/10794 has a couple of charms that show that basically when you set relation data you can add a --app flag that states that this is part of a single application level data bag that charms can use. I’m not sure where the frameworks are at picking this up yet as it’s just out in the 2.7 but the goal is that this means we can watch for when that application level data changes vs checking unit by unit and hopefully reduce chatter and complexity in charming.
