I can see why you read it that way, Spheroid, thanks to my imprecise wording. The point I was making - badly - was that if the Jag was one of the aircraft types it was meant to replace, what was then EFA could not be just an air superiority type only since it wouldn't meet the RAF requirement.
While I'd want to check, ISTR that it was at one point also trumpeted as a replacement for the remaining AD Phantoms as well as the F3 and Jag.
