Why would something that only applies to probably 0.01% of humans be mentioned in a book made to be understood/followed by everyone? Especially when Islam always allows for exceptions based on good faith, reasonable terms and best effort. That's why you can eat pork if no other food is available, or drink alcohol for medical reasons (mostly surgery, back then). You are also allowed to not fast whenever you travel, so it's not like exceptions on fasting rules can't exist. So with that framework, it is not needed to have every single little quirk documented. But it sometimes also requires islamic experts to confirm what would be reasonable and reassure those who haven't read or understood everything in the Quran. You really can't look at Islam as a completely rigid list of potential gotchas. And there's no equivalent of a clergy or a pope, so you have to think of those experts' interpretations as more of a "legal opinion" instead of religious or divine mandates. (It's also why it is funny whenever I hear about people dunking bullets in pig blood or whatever when fighting against muslims, because they think that will send them to hell or something. As if intent isn't super important in Islam!)
