Agreed on the taste and "texture" of distilled water. At the same time comical, to be questioning plain 100% pure distilled water as if it were poison. And if any of us were to guzzle 4 gallons of it in a day, we would either burst open, or spend the whole day behind a tree. And that would be about the worst of it. But photographic chemicals would love it. Contamination-free. Haven't we all got enough other variables? My policy is all developers get mixed in distilled water. That's the 1 chemical that you don't want to risk contaminating.
