Neil I'm assuming you are asking if http2 is backward compatible with http1. Because http2 improves framing; adding binary compression, the ability to push from server to client, and simultaneous connections - it is absolutely required that both server and client know the implementation this allows abstraction of implementation from the application too.
Good news is that all major browsers have supported http2 since about - and Node as a client does too. Node, Nginx, and Apache offer it server side - so most use cases are covered. Its a vast improvement. Thanks for the reply Rik — Neil. Without library it could be buggy just to point out.
