"This repository is now archived. We only tracked up through 3.1.7 and then, because it became too difficult as OpenSSL added more code to their implementation of QUIC, we moved to becoming a full fork of OpenSSL. We encourage you to see that respository's README If there features you would like to see from more recent OpenSSL releases, please report an issue, or -- better yet :) -- make a pull request"

Фига, они таки форкнули openssl, и теперь "сами по себе мальчики" - https://github.com/quictls/quictls/
