After having fixed one of my packages to address this (should have done this first, sorry!), I have tried to streamline this process. I have written a comprehensive
/usr/share/doc/python3-qtpy/README.Debian.gz explaining how qtpy works and how to determine the dependencies required. I have also written a script to calculate the Debian PyQt5/PyQt6/PySide6 dependencies from a list of imported qtpy modules, called qtpy-get-dependencies(1). These can be found in python3-qtpy 2.4.2-4 (unstable, waiting to migrate to testing) and 2.4.2-5 (experimental, which has again dropped the PyQt5 dependencies from python3-qtpy). Best wishes, Julian
