I would argue the opposite. 707 pilots didn't have to fly CDA's to an RNP approach... oh and 38 knot crosswind limits....
Oh really?! When I flew the B707 our take off crosswind limits were 30 knots gusting 40 and landing 25 gust 35 - as near as dammit to 38 knots and a bit of journalistic licence was applied at certain destinations like Bermuda where we only carried island reserve and the runway was permanently out of wind.
