HTTP stopped being a datagram-like application when AJAX and 
streaming video became popular.
Yes, there's a message-passing framework still inside it,
because it does some useful things and it's hard to make it go away,
but that's not what people are doing with most of the bits.
It's a somewhat different use case than fetching web pages.

(Attacks like Slowloris or Slowhttp are also somewhat different,
but it's not really necessary for TLS ver N+1 to support those efficiently.)
