RedHat also stuck with their own custom-crippled version of Perl for 2 years. That's long enough. It feels like you are implying a piety and competence in the vendors and an insanity in the Perl side that is not supported by the facts.
Though I personally don't expect the OS vendor to build or support the Perl I want to use for development at all. They can have whatever they want and we can have whatever we want; if lucky enough to work in that kind of shop. No one has to be a loser or a bad guy.
