Cpan is being used to keep a perl-installation "current". Running it on Fedora (or other system which come with a vendor supplied perl), replaces all "non-current" perl-modules with those which are marked "current" in CPAN. I.e. to keep the difference between CPAN and a "vendor supplied" perl minimal, it's advisable to keep the "vendor supplied" perl in sync with CPAN. Or to put it differently: To keep a vendor supplied perl usable for perl developers, it's advisable to keep vendor-supplied "perl-modules" as close as possible to CPAN - This had been the strategy in Fedora ever since Fedora is around. Or differently: If we don't keep perl-modules in Fedora's perl "CPAN current", we sooner or later will not be able to add other perl-modules to Fedora or to upgrade other perl-modules, which e.g. carry hard-dependencies to these "not upgraded modules" to Fedora Or yet differently: CPAN and rpm are colliding packaging/installation systems. Finally: Keeping perl-modules in Fedora in sync helps users from "killing" their "vender-supplied" perl installation, by mixing it up with CPAN - Issues resulting from such kind of mixtures very commonly are the cause of issues perl-users are reporting against Fedora's "perl". > Nothing of consequence (at least according to the source changelog) > changed with respect to perl in F11.

Wait until you will want to address a "serious/critical" bugfix to a perl-module which carries a dependency on a perl-module you haven't kept in sync with CPAN => You'd have to resort to either "fastestly" upgrade a series of perl-modules or resort to other solutions (E.g. to deliberately remove versioned dependencies from rpm and try to get away without them.)
