I believe you are in error here and the filing is correct. The
dependency requires a python3-pyvkfft with a suitable version to be
configured before python3-pyvkfft-cuda can be configured. However,
Depends (unlike Pre-Depends) does not impose any restrictions on
unpacks. Therefore python3-pyvkfft-cuda may still be unpacked (but not
configured) with an old version of python3-pyvkfft still being unpacked.
In this situation, you may see an error from dpkg. This problem may even
occur in a practical setting during upgrades. The package manager may
choose to unpack python3-pyvkfft-cuda before unpacking the upgrade of
python3-pyvkfft.

I don't think this is necessary given the above.
