Yeah... I guess a little bit it does. Keybase offers an alternative to Web of Trust that kernel.org itself uses (https://www.kernel.org/doc/wot/). Keybase solution is having multiple social-proofs instead of the Web of Trust. Sadly this is unnecessarily centralized but I've seen approaches to implement Keybase-like social proofs systems in pure OpenPGP: https://github.com/wiktor-k/openpgp-proofs#openpgp-proofs
