keeping unused library is not worst that keeping old perl modules.

A few wasted mega of disk space do not seems to be big problem if that
permit to have more people on rawhide, faster tests and faster feedback.
The priority for rawhide should be having something that work first.

And I think the problem could be solved ( and in fact, it is already a
problem we have for those that install something, then remove the main
software without cleaning deps ).

We should not refuse  the idea on the ground that this is too complex
for some users to understand the concept of soname. Either they don't,
and then we should just hide libraries from the UI at some point ( and
that's already done ), because with or without soname, that will not
change anything, or they are able to understand and then we should not
treat them as they couldn't.

So 2 drawbacks do not seems much, or at least not "several".
Can you maybe explain others issues so we can find a solution that work
fine ?
