It's good initiative, Perl way of answering to the dead question.
When users publish modules on CPAN they do not prohibit to redistribute modules.
So we can redistribute source code via github, bitbucket or so.
This will increase perl popularity and shows to public how perl is amazing how it wide spread, how many code is available how it supported and how modules updated often.
Unfortunately tools do not take into account CPAN and measure is made via just popular platform like: github.
Hope this will be useful ;-)
