It is a kind of fuzzy signal though. Maybe a better replacement could be found. Like, if we all had PGP keys, we could just sign the article that we like, right? Then, a web-of-prestige that more accurately represents the field could be generated. ORCID could manage it, haha.
Publishing collusion rings would greatly enjoy using this web-of-prestige: https://www.zmescience.com/science/news-science/a-massive-fr...
Well, yes, this is exactly the kind of well-intentioned technical solution that just will not work at all when it comes in contact with human nature. "Oh boy my paper got accepted in Nature!" vs - "oh boy some people on the internet signed my pgp thing!". Just not the same.
