I want a network of trust, such that a Google reviewed package is worth 10 points, a package fuzzed by foobar is worth 2 points, something skimmed by a dependant user is worth 1 point etc.
I can then chose a compromise between a highly rated/reviewed dependencies and functionality/risk/cost-to-review.
My own blessing of a package I have reviewed might become a very small signal in a web of trust.
