One use case for the question label is a bit of code that you're unfamiliar with, but which is commonly used by more experienced developers. That said, it can be a good primer for the author to update the code, add explanation, or use simpler code structures so the code becomes more obvious.

Like, "what does ??= mean? I've never seen it before" in modern JS. I've had to adjust to code like that for a bit because I've been doing JS since ES3/4 and may have missed some developments (or the general availability of those).
