This means that the only place where we are currently "bothered" by an artefact's name is the "Core Exttensions" and "Intalled Extensions" sections and maybe the dependencies section of another extension. The main browsing and searching view is done only on XWiki Repository extensions and here we only expose top level stuff as you said.
