Expected behaviour

With opencv-python-headless-4.5.5.64 I was able to import opencv module into Python alike:

from cv2 import (
     cv2
)

this way any related functionalities could be accessed, for example via cv2.putText.

Actual behavior

Since yesterday, opencv-python-headless-4.6.0.66 gets pulled.
Any automated build pipelines now break with the error

$ pytest --cov=lib tests/ -v
ImportError while loading conftest '/home/gitlab-runner/builds/QWycMLvj/0/ulb/ulb-it-migration/tests/conftest.py'.
tests/conftest.py:15: in <module>
    from cv2 import (
E   ImportError: Bindings generation error. Submodule name should always start with a parent module name. Parent name: cv2.cv2. Submodule name: cv2

Steps to reproduce

• example code: please see above
• ubuntu 20.04 LTS
• x86
• opencv-python-headless-4.6.0.66

Issue submission checklist

• This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
• I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
• The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
• I'm using the latest version of opencv-python
