I agree with you— that was a lot of drumming for what turned out to be kind of a nothingburger as far as the "bug".

At the same time, putting this kind of thing in a library (or even a language's stdlib) is worthwhile for exactly this kind of reason— it allows devs to confidently reach for code that other smart people have really agonized over and which definitely covers the corner cases, similar to other common utilities such as sort methods.
