I see no evidence posted, please provide besides memory. It could be they were not on all vendors / town locations, name / location changed from beta so confused people, spoiler sites did not list them so no one knew where to find / research them, your memory betrays you, etc.
You could 100% be correct, but I don't see devs implementing this without some evidence to this issue and evidence as to when they would have been put in game.
