Playing with Alias' new CPANDB

This is a somewhat simple query that identifies CPAN authors that use modules from the Test namespace in their runtime phase, according to the data from CPANDB. SELECT d.author, count(r.module) AS test_namespace_used_in_runtime_phase FROM requires r JOIN distribution d ON r.distribution = d.distribution WHERE r.module LIKE 'Test::%' AND r.phase = 'runtime' GROUP BY d.author ORDER BY test_namespace_used_in_runtime_phase DESC LIMIT 20

Some modules might actually require modules from the Test namespace in their runtime phase, but this many? I would think that this is an indicator that some authors mark their test requirements in the wrong way (or CPANDB is wrong). Maybe some Makefile.PL cleanup should done?
