The output of the project so far includes (as of tomorrow) 27 releases of Rakudo (Perl 6 on Parrot). There may be plenty to criticize, but "not releasing software" is not one of them. A better line of criticism is "Why is it necessary to reinvent regular expressions and spend a couple of years researching how to produce lexically scoped mutable grammars?" -- but once you understand why that's an interesting question, you'll probably have noticed the 27 releases of Rakudo.
I've had working software in Perl 6 for four and a half years.
