Sure.Gary said something along those lines in the 1e DMG, followed immediately by, if it won't make the game worse or would make it better, then of course you should engage in realism.
Basically, he's saying that making people have their characters go to the bathroom X times a day, every day would be unfun as all heck, but other forms of realism might not be that bad, so do it.
But the core point remains: even from the very foundation of the hobby, even from the moment that what most folks see as the highest height of ultra-realism, generally-respected folks recognized that overly-laborious focus on realism wasn't actually productive. That there are, in fact, times when it is NOT correct to choose greater realism and damn the consequences. That, even to people who prize realism extremely highly, it is NOT universally better to maximize realism absolutely every single time. It didn't come from some yahoo nobody knows. It didn't come from "storytelling" games. It didn't come from a newfangled thing that can be dismissed because it's just a fad. It can't be written off as merely an isolated separate preference totally unrelated to sandbox-y play or "traditional GM" games, because this was very specifically in a context everyone agrees is unequivocally sandbox-y play by the man who defined what "traditional GM" meant.
There have been many arguments, here and elsewhere, where folks have presented the thesis, often in different words, that if you have a choice where option A is more realistic and option B is less realistic, it is ALWAYS, 100% of the time, regardless of context or cost, absolutely always best to choose A, no matter what A or B might be, because A is more realistic and B is less. It is useful to me, to point to something that has none of the characteristics used to casually dismiss my arguments.
It is a useful way to show people that realism is not a cost-free choice, and that sometimes, the cost can be too high.
