Just my to cents comment :
But shouldn't this just be 'normal behaviour'? When I have a package installed and I want to reinstall or update the package, doesn't it seem logical to replace updated files?
I think that a 'normal behaviour' may change with another person opinion.
Some people may want to install a new module and keep a previous version (for testing pupose).
Some people even find it normal to have a Perl 5.6 WITH a previous perl version.
