+Tried it.
+Being cautious, I left about 10 of the 50 or so packages listed.  Most 
+listed were obviously useless, but otherwise hard to find.  Used 
+rpmdrake to see their descriptions and remove them.
+Some of the packages seemed to be used by others, if I'm not mistaken.  
+Maybe by suggests ?
+
+For everyone's info, -g alone scans System/Libraries.
+Using -g {group} will scan whatever other group.
+
+In sum, a useful tool if used cautiously.
+A lot better than task-obsoletes or whatever else that would remove 
+packages indiscriminately and/or automatically.
