+#### New `InstanceMetadataService`
+
+While we could attach the existing information to the `PluginMetadataService`, we propose a new service that handles instance-level information. The existing `PluginMetadataService` should reveal information about the plugin itself, its pluginId, dependencies or similar. The new `InstanceMetadataService` should give you information about the entire Backstage instance that you're interrogating. At launch, this should include the list of plugins installed _on your instance_ that can then be aggregated by the discovery API across the gateway nodes. One could imagine this service also having information about instance URLs, health or gateway status.
