I understand that p5p peoples wont maintain a big mole of modules. But is not the majority "dual life" modules? p5p maintain directly all modules in core? Would not be possible make a release of Perl with up to date modules from CPAN?
When you'll need a more recent version of a particular module you'll upgrade from CPAN.
