I'm glad you agree that knowing someone's name, age, and address doesn't prove their trustworthiness, because I don't want trust decisions to be dependent on threats of state-backed violence or mob vigilantism.
It is possible to build up trust in an identity based on how long that identity has been used, and the "transitivity of trust" principle. So you wouldn't trust someone because "John sounds like a trustworthy name", and instead you'd look at how long the author's key had been associated with the library, and whether their key had previously been endorsed on other people's projects (for example having their PRs reviewed and accepted).
Admittedly this introduces a new danger that the social graphs start to become very dangerous honeypots of metadata, especially if we start letting employers vouch for their employees, but the ultimate goal here should be to use something like Verifiable Credentials with zero knowledge proofs, which will allow very strong probabilistic arguments to be made about whether an author (and all the code reviewers) have suddenly gone rogue and decided to burn their hard-earned reputations.
