It causes failure of CMake commands like

In latest Debian/testing, python3-numpy has added a dependence on libpython3.9-minimal libpython3.9-stdlib python3.9 python3.9-minimal. This breaks compatibility with packages like python3, python3-dev, libpython3-dev that depend exclusively on 3.8. find_package(Python3 COMPONENTS Interpreter Development NumPy) Is there a way to clarify once and for all that all Python3 packages with unspecified minor version ought to depend on the same minor version?

This has been a known issue with CMake and has been fixed there. Closing this bug now.
