Created PR to remove it https://github.com/wildfly/wildfly/pull/9286

It removes all runtime related things, but keeps mgmt stub, so latest DC can still manage legacy HC.

There have also be complains from community why we downgraded the PicketLink in WF10
and now there is a migration problem from WF9 --> 10. [1]

If we remove it, we would just keep the mgmt stub so we can still manage mixed-domain with older versions.
Similarly as we did with osgi & friends back in the day.
It was already deprecated in 10, so we could remove it in 11 or later.

This is a pretty strong reason to remove it, if on top of deprecation, most of its users in community want a different version
