Very true. Actually HTTP now also just refers to the semantics. HTTP/2 and HTTP/3 are still HTTP. They all support requests, responses, verbs, status codes, headers, caching semantics, etc.
The only thing that might become less common is "HTTP/1.1 over TCP". But I get that this is much more verbose to write than "RIP HTTP".
HTTP isn't going anywhere. HTTPS is literally just HTTP with a TLS layer on top.
