I was struggling with the fairness of your comment because the libraries are not used as a replacement to NumPy, but to ease dealing with the data. This made me check and it turns out that:

"Yes, the comment you mentioned is fair and reflects a common perspective in the programming and data science communities regarding the usage of "pure" implementations. When someone refers to a "pure X implementation," the typical expectation is that the implementation will rely solely on the functionalities of library X, without introducing dependencies from other libraries or frameworks."

TIL.
