This article conflates a lot of different topics. If your WebSocket connection can be easily replaced with SSE+POST requests, then yeah you don’t need WebSockets. That doesn’t mean there aren’t a ton of very valid use cases (games, anything with real time two-way interactivity).
No need for WebSockets there as well. Check out WebTransport.

That's a pretty convincing use-case. Why use something standard if it can be non-standard custom instead!
Isn't WebTransport basically WebSockets reimplemented in HTTP/3? What point where you trying to make?
No.
Thanks for your insight.
It seems you need to urgently reach out to the people working on WebTransport. You seem to know better and their documentation contradicts and refutes your assertion.
If you take some time to learn about WebTransport, you will eventually notice that if you remove HTTP/3 from if you remove each and every single feature that WebTransport touts as changes/improvements over WebSockets.
