Trying to get the significant number of upstream perl module copyright
holders to fork and relicense would probably be a fruitless adventure.
In fact upstream perl module developers may be reluctant to deviate from
Perl's copyright, quoting the FSF [1]:
License of Perl 5 and below
This license is the disjunction of the Artistic License 1.0 and
the GNU GPL—in other words, you can choose either of those two
licenses. It qualifies as a free software license, but it may
not be a real copyleft. It is compatible with the GNU GPL
because the GNU GPL is one of the alternatives.
We recommend you use this license for any Perl 4 or Perl 5
package you write, to promote coherence and uniformity in Perl
programming. Outside of Perl, we urge you not to use this
license; it is better to use just the GNU GPL.
