noo not the cgi module :(
The complaint is that the module is designed poorly, which is fair; to remove CGI support without any "batteries included" replacement seems a bit of a shame, though.
What's actually in the module is a rather clunky, but serviceable, system for processing html form data.
Perl removed CGI from its core back in 2014 - https://perl5.git.perl.org/perl.git/commitdiff/e9fa5a80
