Not sure if this is caused by anything in the implementation itself, but on Ubuntu in VS Code mypy is reporting missing library stubs in the plugin.py file for all imports from the qgis package.

Skipping analyzing "qgis.core": module is installed, but missing library stubs or py.typed markerMypy[import-untyped]

Similar error in build.py:

Cannot find implementation or library stub for module named "qgis_plugin_tools.infrastructure.plugin_maker"

Looks good to me, although I might have missed something in my testing since I did not get the same error as @JuhoErvasti

I ignored those missing type errors on qgis and osgeo package. And for qgis_plugin_tools all typing errors completly.
