I have edited this down to just the single real question.
08:57:05 mst> cfedde: CGI.pm is deprecated and scheduled to be removed from
the core as a terrible idea by 5.22 at the latest
I check the module doc and I don't find a deprecation notice in it. Neither does there appear to be an "official CORE" deprecation list.
Is IRC where we go to find out that a module is deprecated?
