Then again, sometimes a big feature is so comprehensively broken that it’s hard, from the outside, to break it down into specific flaws. Even if you can reproduce the complex circumstances where they manifest.

In the case of the iOS keyboard, I remember one bug that made the rounds (in the popular press!) after somebody recorded their typing in slow motion to validate it [0]. Once they documented it, everybody recognized the feeling and felt vindicated; but it took actual work to substantiate.

That’s the work it seems that Apple engineers should be doing. They have the telemetry, the source access, the design documents, the labs, and the time in their day to make a comprehensive study of it. Just as I can say “my car is handling funny around turns” and let it be the mechanic’s job to diagnose what’s wrong in mechanical terms.

There was a time when this humane aspect was Apple’s particular magic: engineering beyond technical requirements to the point of simplicity, ergonomics, “it just works”…
