That's true, but the transport layer has ossified, and the application layer is the only place we can still innovate. RIP SCTP.

Still sad, it would have been much nicer to just keep HTTP as is and just put in a different transport layer. Or maybe extend HTTP a little but right now we've got a protocol independent HTTP/1.1 and a new HTTP/3 which rather than being more general strictly relies on a single protocol.
