Did the title scare you? If so let me know :) We are debating on deprecating the support for domain mode in the WildFly Arquillian Adaptor. 

The main reason is I'm terrible about remembering to port fixes that go into the standalone adaptor to the domain adaptor. Plus, looking at the available stats I do not see the domain artifacts being downloaded at all.

If you use domain mode with WildFly Arquillian, please let me know. Otherwise, we are likely going to deprecate and remove the support.

Thanks in advance!
