Yes, I agree - From-Origin is a more generic mechanism.

This goes back to our discussion about consistency. There is nothing that would preclude us from having different defaults introduced for backward compatibility (where absence of From-Origin header would be considered as "From-Origin=any", and for everything else including fonts where absence of the header would be treated as "From-Origin=same"

This would offer the best of both worlds solution - a generic mechanism that is backward compatible and works with all existing resource types, and also the one that requires no extra work for the majority of authors.
