This JIRA comes to us from CSAT list tracked here:
https://mojo.redhat.com/docs/DOC-1130004#jive_content_id_October_2017__CES__Documentation

And is specifically to track the issue highlighted in RED text below:
The product has many defects or regressions that needs a lot of investigation to make it work. The documentation is changing (interceptor appeared in the documentation after the initial release), incomplete (for instance, the bridge and the divert are not documented) or incorrect (e.g. interceptor documentation is incorrect on the configuration file). A simple action as a patch release install created a regression (the actual case) and required a workaround to have it working.
