So the task force can decide the behaviour rather than pre-empting their 
conclusions with a MUST or SHOULD that is only relevant after they have 
decided.  Given that at least one likely conclusion will be a whitelist file 
allowing cross domain from such sites, your use case is met without 
endangering user freedoms.

Because anything included in an IFRAME or new window is already trivially 
able to be retrieved without a referrer header in the vast majority of UAs 
that support script today.  The only things you cannot do is add an image 
with img (you can with iframe) or css background or content in an embed 
element, so the only relevant protection you're introducing is in these 
formats, not simple HTML or text documents.
