net/http: documentation for interaction between http2 imported and http pkgs.

[yonderblue]

Just requesting some documentation for the case when someone does something like

hs := &http.Server{Handler: thehandler}
if err := http2.ConfigureServer(hs, &http2.Server{}); err != nil {
    //handle
}
if err := hs.Serve(existingTLSListener); err != nil {
    //handle
}

and has therefore vendored in the http2 package. How does this interact with the bundled http2 in the http package?

Any kind of one sentence answer here before documentation is worked on would be highly valued if anyone has the time

If you import golang.org/x/net/http2 and use it to register the client or server, the (presumably newer) http2 package you imported wins.

The bundled copy is only used as a default.

Much appreciated, but which in the example above is doing the "registering"?

http2.ConfigureServer
