It most probably should be part of the AS integration, as we only add it to the DU we don't need the deployers to depend on it as well.

This then would exclude all non EE5 deployments from annotation scanning without a separate jboss-scanning.xml. As far as i can remember for servlet 3.0 we would need be able to exclude resources on .jar basis as well.

Yeah something simple like that should be enough. 

We could also add some simple deployers to the 5_x branch - at least generating a empty ScanningMetaData for isMetaDataComplete() does not require Papaki. This could speed up legacy deployments quite a bit, as we wouldn't process the already scanned annotations anyway.
