It's a common misconception what CPAN is. CPAN is a distributed archive where users may store perl-related resources for public use. Additionaly there's a little bit of infrastructure around it (a permission system for module namespaces etc.)
Anything else is just an add-on around the core CPAN. search.cpan.org is just a useful view at CPAN, but it must not be the only one . In fact, there's also kobesearch providing an alternative view. There you find a listing of PPM packages for Win32 for every distribution.
And it's quite easy to provide an additional view to CPAN. Recently I wrote the CPAN Testers Matrix because I was not satisfied with the test report presentation on cpantesters.perl.org. Currently it's ennobled by being linked from both search.cpan.org and kobesearch.
I happen also to like the cpanratings. It's usually the first page I am reading each morning.
