Advanced REST Client and API console uses this component to render XML data. We want to retire this component as it does not give any advantage over using Prism library (right now this library is being used to render other types).
The component also causes problems when integrating it into other systems because it uses web workers. I have received many requests to remove use of web worker. My response is always: no data parsing in main thread process as it may cause the UI to hang. Prism also uses web workers but at least we will have one thing less to be worry about.
The "response-body-view" and "response-view" components that uses this component will be changed around July 2019. After this date new version will be released without additional support for XML responses other than Prism highlighting.
See this intent to deprecate here and comment if you'd like to take a part in the discussion.
