What we're discussing here is the response to an authorization request.  
That response basically only needs to say that the server agrees with the  
non-GET request. It's likely that authors don't put a whole lot of content  
in that response as it would not make sense. And even if they did the user  
agent could in theory close the connection after it received the <root>  
element start tag in case of an XML response. (In case of other responses  
the entity body is not significant.)

What I think is unlikely that authors will make requests to arbitrary  
domains of which they do not know whether the other site agrees with the  
request in production sites. Therefore I think it's not likely you will  
encounter this as a problem.
