This should open up other services and apps to become authorisation providers for Home Assistant easily. https://github.com/home-assistant/home-assistant/pull/19985

An example of this is with the new system health component. In order for your installation of Home Assistant to have the new system_health component activated, all Home Assistant users must add the the applicable system_health component to their installation of Home Assistant manually.

Moving forward, with installations that have this new default_config component loaded, Home Assistant can automatically enable new features and functionality, like the system_health component apon upgrade, whilst still allowing users to disable or override the default settings when required.
