I like the second draft a lot, though I doubt that we can give Level 1 for a lot of packages, if the number of people is higher than 5. Furthermore, with each new release this would mean to switch all packages back to Level 0, as we won't have the ability to go beyond Level 1 before the release. Last but not least, how do people report about an installation of a package.
Could you give your estimation of the maturity of some example non-core packages ?
