- It may be possible to mitigate this in the UI by using the "handler" app-type to function as an event bus (since the UI bundle is deployed as a monolith, events published in one module could, potentially, be acted upon by another) but we don't actually have anything like this in production yet. We do have handler-modules, but don't have an established protocol for apps to issue their own events.
