Review comment:
       I like to have the bundle-meta-data in a manifest. Together with the smaller build that is the only reason.
   
   I just packaged everything that was in before. Just because of -conditionalpackage the bundle is 400kb smaller than before!
   
   We are using [BundleStartLevel](https://github.com/apache/sling-org-apache-sling-feature-launcher/blob/14fd3f7476214baf2ee114e71d50f6518fd75fd8/src/main/java/org/apache/sling/feature/launcher/impl/launchers/AbstractRunner.java#L323) and the static field `FrameworkEvent.STOPPED_SYSTEM_REFRESHED` in bootstrap.
   
   not sure how to remove the `BundleStartLevel`
