I wouldn't say summoners are taboo. They are just more rare, even by Job standards. (And that's saying something.) So Summoners originated from the time of the Allagan Empire circa 5000 years ago. They and their power to control primal essences has not been experienced since that time. Now in the storyline, the Player Character is the first to experiment unlocking these powers but probably won't be the last.
I believe that because summoners are Allagan, they wouldn't be met with too much resistance to the general adventurer community. Allagan anything and everything is all the rage in Eorzea right now. Allagan books, Allagan armor, Allagan tomestones, Allagan ruins, etc etc. I think the idea of the Allagan Summoner revival would be taken quite well by the public. However, seeing the Primal Egis in action might not go over so well. Primals are terrifying and people have good reason to fear them. Seeing even a baby version of such Gods would probably terrify most people.
