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.
