What makes the fact that each hook call needs to be associated with an index so unacceptable?

  You could say each call corresponds to a timestamp and they need to be ordered, and the person receiving that information would be none the wiser. It just doesn't lead you to understand what's happening underneath. Some may be fine with stopping at that level of understanding, but the stack-based approach of hooks is quite unnatural for JS and I don't think it is good in the long-term for developers to just 'accept' that as supernatural.

    So in order to understand not only the basics of the rule, but also the underlying implementation and exactly in what way it would crash, it may require more than a paragraph. I'll concede that. But this is common in programming. As an example, you'd probably spend some time understanding exactly why it is you can't free a pointer twice in C. There's nothing stopping someone from reading the explanation in the React docs[0] if they want to understand.
