If they released support for this header with Firefox and Chrome, almost immediately, people wouldn't bother hotlinking to sites which utilise it because a good proportion of their users wouldn't be able to see the content at all.
Of course, even if this was released today and referrers were phased out in June 2014. We'd still be able to use them for at least 5 years until you could safely assume that they were gone. Likely longer.
