Actually, it's asking, "Most other duck-typed methods will still raise a TypeError, but these few don't. Has that ever been a problem for you?"

I don't think I've ever been bothered by getting an AttributeError instead of a TypeError or vice versa. Both indicate bugs in my code, and I debug it by looking at the code and traceback; I don't try to guess the problem based solely on the exception type.

In this case the code would have to go out of its way to turn an AttributeError into a TypeError. I don't think the cost of that is worth whatever small benefit there might be, if any.

Summary: Looks fine to me as it is.
