Hm, seems to me like an additional layer of abstraction, which is not  
necessary. The user agent could send the OpenID URL directly, e.g.:
  Link: <http://mysite.org/>; rel="openid"

But I have to agree to others, mostly you don't want your browser to send  
your identity to every site you visit due to privacy reasons. However, as  
an option, possible.

By the "bit of magic" you propably mean that the browser doesn't have to  
do the redirect circle to the OpenID provider and back for autologin.  
There are already multiple people in the OpenID community working on  
different proposals how OpenID login can be automated even in cases where  
we have a non-browser user agent, but that's all still in a very early
