True, but this could be used to assign "points" to each package. 
Points would be used to show sorted list of unused packages. That way 
top packages would be libraries, at bottom you would find 
applications.

Here I differ in opinion, if you use rpm you are likely not a regular 
user, so seeing list:
OpenOffice
libsomething

  you should also easily judge if it is a library or an app.

Yes, it could be time consuming. But the good news it is possible. 
It could be option not to check the whole system but to 
examine "suspicious" package if it is still required -- this would be 
also useful.

have a nice day, bye
