I could see how RIO would be superior if you played regular table and knew someone is prone to tilt after losing a stack. But I do think you underestimate other regs by thinking they can't handle swings well. And if someone is prone to tilt after getting sucked out once, then getting sucked out twice in same pot should tilt him even more. In which case it roughly evens out imo.
Now in zoom I can't see how RIO could do anything good for you. If you suck out on someone the large player pool combined with hand distribution makes it very very unlikely that you could possibly take advantage of someone steaming.
If someone knows that you RIT they may get in lighter if they are somewhat scared money and make emotional decisions which is likely a good thing too.
Overall I don't think it's as clear cut if you gain something or not edge wise from RIO or RIT. And even in high stakes regulars do disagree regarding this matter.
But since it's a fact RIT reduces swings and only a guess that RIO gives you more edge I choose to go with facts .
Reducing short term swings isn't unprofessional when something nearing long term is 500k+ hands. And claiming it's just weak players excuse is just lol.
