Where does that document say that WebTransport is just WebSockets over HTTP/3? The only thing in common is that both features provide reliable bi-directional streams, but WebTransport also supports unreliable streams and a bunch of other things. Please read the docs. There is also RFC 9220 Bootstrapping WebSockets with HTTP/3, which is literally WebSockets over HTTP/3.

He said "basically" which should be interpreted as "roughly"? Then it seems his assert is roughly correct?

Maybe? Isn't WebSockets basically TCP? Roughly? I wrote that WebSockets provide reliable bi-directional streams, but it actually doesn't. It implements message framing. WebTransport also doesn't support "unreliable streams", it's actually called "datagrams". WebTransport doesn't even have to be used over HTTP/3 per the latest spec, so is it basically WebSockets reimplemented in HTTP/3? No.

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.
