Currently http2.Http2ServerRequest.headers returns headers which is initialized by Object.create(null) which is a different behaviour than what is seen in http.

The use of Object.create(null) in http/2 is intentional. For HTTP/1, the reason we do not use Object.create(null) for headers is because it would break too much code but it would have been preferable. I don't think this is one we want to change. A code comment to that effect would be good.
