> Due to SLING-5664 I had to remove usage of {{SlingScriptHelper}} in the 
> {{OSGiServiceInjector}}. Therefore now always the 
> {{DisposableCallbackRegistry}} is used to release service references. That 
> mechanism relies on a dedicated thread 
> (https://github.com/apache/sling/blob/b864f105617c0ac7c2d525bfdb66eda2200c6460/bundles/extensions/models/impl/src/main/java/org/apache/sling/models/impl/ModelAdapterFactory.java#L133)
>  and phantom references 
> (https://github.com/apache/sling/blob/b864f105617c0ac7c2d525bfdb66eda2200c6460/bundles/extensions/models/impl/src/main/java/org/apache/sling/models/impl/ModelAdapterFactory.java#L504).
>  In case of acting on top of a request one could leverage 
> {{ServletRequestListener.requestDestroyed(...)}} instead, which is more 
> reliable and called earlier than relying on phantom references.
