For me the gross smells are artificial fragrances like soap, deodorant, cologne/perfume, and dish soap. I don't love car exhaust. Dish soap especially smells _so gross_. It's just so chemically and strong. I do find dish sponges left out start to smell like mold to the extent that it makes it hard to use. That's why washing dishes is rough, I get mold from the sponge and chemicals from the soap.
I do think though it's just genetic. Also I think dogs don't smell bitter scents as strongly as we do (it's how they can eat feces). So mold might not be as gross for them.
Its meta data on peoples health. Look at long covid and the loss of smell. Symptoms indicating what people are missing out on dietary wise in order to improve their health. Thats why I say Covid was a biological weapon, and there are plenty of people who know what they know, but they dont know what they know...

Coprophagy and bacterial analysis studies suggest there may be a need for certain vitamins, namely vit K.
If brands see that increasing the amount also increase sales without increasing the risk - they're likely to do that - which could numb the sweetness of anything else.
Given how sensitive consumers are to changes in its taste, I think the overriding concern for Coke would be not changing the flavor of the formula.
I'm not sure anyone's clamoring for sweeter drinks. Non-diet drinks like Coke have an established recipe, and diet sodas approximate the same balance of flavors.
Anecdotally, even as a kid, I found Skittles to be unpleasantly sweet. To this day, I avoid most sweet soda drinks and seldom drink even those I can tolerate.
It is not discipline for me. It is not even taste. It is tolerance.
My brother has a young (but large) dog who is still trying to taste everything. Yesterday he was excavating and devouring(?) some tree roots with great enthusiasm.
At least it distracted him from wanting to chase moles and deers.
Also his treats smell abysmal, but obviously he likes them.
