  Perl 4 was bad, all the "not enterprisey" enough comments are about Perl 4 which also was used a lot in enterprises and caused unholy messes, some of which still echo after more than 20 years

  Yes, I had to maintain Perl 5 code hastily ported from Perl 4 around 2014, and it was ... educational.

  As long as it resulted in unique-looking websites for projects rather than them all looking the same, I agree that a Dist::Zilla plugin would be a cool idea.

  Overall the aim is to have lots of small loosely-interconnected Perl websites, rather than everything just being on a few big websites. (Though those big sites should absolutely also still exist!)
