The lore says that of a lot of advanced classes - first one since ever. People will adapt to the restrictions in different ways. It's fine to stick to it very strictly (I personally prefer to, too), but not everyone has to. Nobody needs to back anything up to the Lore Police.
That being said, I stand corrected - not the skills of a dragoon specifically, but dragoon-like skills, at least. The moves, but little else. Although, one can consider that it is possible for a foreigner to be chosen by the Eye - just extremely rare - so if someone wanted to say they were chosen, they technically could. Again, I myself would not, but I wouldn't judge if someone chose to play it from that angle, either.
