No. CERN (aka, Tim Berners-Lee) came up with HTTP and HTML, but he built on top of TCP/IP and DNS.

QUIC is going in that direction, by running on top of UDP.

In any case, without replacing the protocol stack we already have different webs, thanks to the walled-garden nature of modern social networking platforms. Linking to an Instagram reel or a Tiktok video is a pain in the neck; if you do not have an account there's a good chance you won't be able to see the content anyway. X is going in a similar direction. This (as well as their non-textual nature, of course) makes them hard to crawl and index for search engines. Fragmentation and niches inevitably ensue.
