Hi Kristof,

I am part of the effort for creating high quality stubs for all PyQt 
variants.

You are correct that the default stubs provided with PyQt6 are not 
suitable for typechecking with mypy. They are provided mostly for 
type-completion.

As you found out, we have a work-in-progress project for PyQt6-stubs. 
Like many open source projects, it progresses with volonteers 
availability and recently, progress has been low on this one. I intend 
to change that during August.

Don't hesitate to file an issue over our GitHub, we will do our best to 
look into it.

Cheers,

Philippe
