Are all CPAN modules supposed to be listed on metacpan.org?

Hi,

I'm looking into broken URLs of Fedora packages of (inter
alia) CPAN modules, in the following picking
https://src.fedoraproject.org/rpms/perl-Config-IniHash as a
random example.

This Fedora package refers to
https://metacpan.org/release/Config-IniHash which redirects
to https://metacpan.org/dist/Config-IniHash which is 404.

The source URL however,
https://cpan.metacpan.org/authors/id/J/JE/JENDA/Config-IniHash-3.01.01.tar.gz,
works nicely, as does some metadata file at
https://www.cpan.org/modules/by-authors/id/J/JE/JENDA/Config-IniHash-3.01.01.meta.

If I go to https://metacpan.org/author/JENDA, Config-IniHash
is not listed there.  If I search for "Config-IniHash"
(https://metacpan.org/search?size=20&q=Config-IniHash) or
"Config::IniHash"
(https://metacpan.org/search?size=20&q=Config%3A%3AIniHash)
on metacpan.org, I don't get any pertinent results.

Therefore I'm interested if this is the expected result or
some fault at (meta)cpan.org and thus who I need to contact
to get it fixed.  Does the module author have to click some
button to trigger the inclusion in the database?  Are all
modules available at cpan.org supposed to be listed at
metacpan.org?

TIA,
Tim
