It wouldn't be the worst event of that type or even unprecedented. HTTP/3 is not even TCP and barely HTTP anymore. HTTP/3, QUIC, was openwashed through the IETF by google/ms/apple and can't even connect to a website unless that website gets continuing approval from a third party corporation for existing (a CA TLS cert, no self signed, no plain text). It is "secure enterprise HTTP" with every one of it's architectural and implementation choices being driven by the needs and use cases of for-profit enterprises. It is a fairly crap protocol for human persons and the web and sites as we know it.
