Perl HTML::Parser missing for RHEL-7 perl520 onwards

Are there any documents to explain why packages such as perls HTML::Parser are included with the old version of perl on RHEL-7 (5.16) as perl-HTML-Parser, but missing from the perl 5.20, 5.24 and 5.26 bundles ?

While I can normally grab and distribute them from cpan in the lab, when building on openshift, I really don't want to be dynamically pulling from CPAN and relying on an external site that isn't a vendor for security and integrity
