Conceptually, keeping old Perl modules is just as bad. Our Perl packaging
does not keep old versions lying around either!
Practically, libraries tend to be a lot larger than Perl modules.

Old libraries accumulate over the lifetime of an installation, eating many
MiB, not just "a few".

It feels really wrong to design a whole library packaging policy around
Rawhide. The focus needs to be on making stable releases clean without
useless legacy compatibility baggage, and Rawhide needs to be the
development bed for that. Compatibility libraries only make sense where the
packages cannot be ported to the new version in time for the release.

The solution for that problem is called yum history undo, and it doesn't
solve the old library problem.

IMHO, having KDE 3 libs versioned as kdelibs4 is totally unacceptable. It's
really confusing. (The only worse way to do things is to append an
unreadable suffix for the C++ ABI to that as Debian did with "kdelibs4c2a".
But if you insist on keeping old ABIs around for any and all ABI changes in
Rawhide, we'll eventually end up with the same mess!)

Sorry, there is just no solution that can make soname-suffixed libraries
work.
