As far as I can see here in the discussion the much newer systems still don't provide for side slip in calculating the actual wind.
that is because rudder inputs on the B744 do render the fmc wind reading invalid. No rudder input, and the fmc give valid winds and readouts are simply good airmanship in challenging conditions.
