I think it is rather more related to team size than codebase size, really. Think of how much can be done with a small group of people who all speak the same dialect / lingo. If everyone is on the same page WRT code style, then TMTOWTDI is just the magic that allowed you all to arrive on the same stylistic page. Perl 6 is much better than Perl 5 in this because some of the styles that ossified in the Perl 5 dinosaur brains are truly grotesque to behold when deployed in the 21st century.
