Lintian tag information: debian-rules-uses-supported-python-versions-without-python-all-build-depends (type: warning)

Description (from lintian-explain-tags)

The package appears to use py3versions -s to determine the "supported"
Python versions without specifying python3-all as a build-dependency.

With only the default version of Python installed, the package may build
and test successfully but subsequently fail at runtime when another,
non-default, Python version is present.

Please add python3-all as a build-dependency.
