OpenCV 5.0.0.93 - `cv2.data.haarcascades` xml files missing

The OpenCV 5.0.0.93 wheels and sdists ship with an empty cv2/data directory. Take this 5.0.0.93 wheel for macOS for example: https://files.pythonhosted.org/packages/50/b9/2a3a9e23d7894f816792f93f2e73c017765a29e854ba343cb260da400a7e/opencv_contrib_python_headless-5.0.0.93-cp37-abi3-macosx_13_0_arm64.whl

It contains only an __init__.py file.

opencv_contrib_python_headless-5.0.0.93-cp37-abi3-macosx_13_0_arm64/cv2/data
└── __init__.py

1 directory, 1 file

The previous 4.13.0.92 wheels (example) do ship with a bunch of haarcascade_* files.

I would expect the haarcascade files to be present in 5.0+ wheels too, since I can't find an explicit mention that these files were removed. Was this intentional or is there a packaging bug?

PS: thanks for the major 5.0 release! Lots of exciting things to look forward to!
