This draft says

Suppose the server supports extended CONNECT but not bootstrapping

I don't think this is correct.  If the client encountered this error code,
it would just fail the WebSocket setup attempt.

In general, I don't think we should be asking clients to retry requests
across different HTTP versions.  If you publish wss:// URIs for your
domain, you need to support WebSocket on all the domain's HTTP versions.
