I also found it interesting because just as the later sections complain about cases where they relied on inferencing "too much", the earliest section also shows cases where they relied on inferencing "not enough". (Had the developer not explicitly typed by copying the inferred type from a tooltip for that D3.js return object, for instance, and left it to be inferred, it wouldn't have been broken in the generics change.)

It's an interesting goldilocks paradox likely only exacerbated by the size of Google's codebase and variety of developer code styles/inferencing preferences.
