I think the most obvious way to attack this is to discuss whether the OE/OS (whatever we end up calling it) draft might specify how UAs MUST/SHOULD/MAY behave when sending a http:// request to a *configured* proxy (when the UA supports OE). 

I don't yet understand the need for different ALPN tokens, cert attributes, etc., unless people are also thinking about non-configured ("transparent") proxies -- which this WG have explicitly and deliberately *not* codified for a long, long time -- or expanding this scheme to also cover HTTPS URIs...
