The metadata for Metacpan is set via the META.json file.

What got me curious is why the Makefile.PL didn't properly set the META.json , because the repo's 'Makefile.PL' sets the METAMERGE => { resources => { bugtracker => {...} } } , but the repo's 'META.json' shows resources: {} as empty.

I've never had ExtUtils::MakeMaker do that to me, and 5 minutes of looking into it has seen me able to replicate the problem, but I don't see why it's not propagating from the Makefile.PL to META.json . Weird.
