Since there is no requirement to track the copyright ownership of contributers there is generally no way to get permission from all of them for a change. Of course a dual license could be applied from the start with one being less restrictive like perl's to eliminate that problem.Such dual licensing would be useless.How has it harmed perl to not force it's users to worry, as this endless thread has, about whether or not some component that it links is too free or not free enough?
It has instead made them worry about the nuances of the artistic license which is far from a clear one.
