I disagree that we should be unconcerned about that. I have heard
plenty of vitriol from developers and sysadmins who experienced
trouble from the Unix/Linux equivalent of DLL hell when installing
software that uses plugins. If the OS vendor or software packager
never makes any mistakes, and if the sysadmin never installs a more
recent version of some software built from source, then _maybe_ it is
possible to ensure that loading the wrong library "cannot happen".
