Why are the stubs for OpenCV's Python bindings still so incomplete?

I mean this.

I think the IDE should provide suggestions for all the functions and classes mentioned in the OpenCV documentation. For example, the OpenCV documentation mentions that ORB_create can be used in Python, but in the IDE, it should provide parameter hints and return type hints for this function.(Currently, ORB_create has no hints.)

I understand, I will go to GitHub to raise this issue.
