What about the URI?
What about the method (GET, POST, DELETE...)?

Only protecting the body only works for RPC-style web services in which every request is a POST to a single API endpoint (eg POST /api/ HTTP/1.1). Even then the body needs to have an "audience" field that is likely to repeat the host (or URI).

HTTP/2 needs to support REST APIs, where the method and URI are crucial parts.

Though I suspect there are lots of headers where this distinction is not crystal clear.
