HTTP has the leeway to do that because they have an easier technical job deploying updates.
If they only got one shot at changing HTTP, do you think they would have tied TLS to HTTP/2 or given up on HTTP/2 altogether?

I don't know if HTTP's job is easier. Maybe on the client side, since there were never that many browsers, but you have load-balancers, CDNs, servers, etc. HTTP/2 adoption is still dragging out because of how many random things don't support it. Might be a big reason why gRPC isn't so popular too.
