From-Origin doesn't allow selectively revoking access to a resource, without
revoking it from everyone.

From-Origin also assumes a very small set of origins which can access a
resource.  If you have lots of domains (Google) or dynamically-generated
domains (Blogspot), it falls apart quickly.

I'd be concerned about losing this functionality of Referer before
From-Origin is fully proven.  I have doubts of From-Origin being a realistic
replacement for it.
