The same argument can be applied to `npm init`, and yet they choose to set the version to `1.0.0`. IMO the argument is that most people are lazy and will use whatever you offer them in the default. By setting the version to `1.0.0`, you are also making it clear that you should quickly get to 1.0 release and don't stay in 0.x land forever like Node core does.

Anyways, this is bike-shedding. I can live with `0.0.0` too. As long as it is not `0.1.0` or `0.0.1`.
