Since the start of AS7 we’ve sought to have a clean separation between “management” and “applications” and this is on the management side but AIUI is being exposed over the normal listener used for apps. There have been other requests along these lines (including a request from very early on to support management as a whole over 8080), and some of the barriers to doing that are coming down. For example in WF 12 elytron should let us support nice inflow of application layer user security identities into management. There have also been requests from the Infinispan folks to support custom contexts on the HTTP management interface. This could apply to that too if the endpoint was on 9090 not 8080.

OK, got it. A server configured this way would act as a config source for other servers. That seems straightforward enough.
