Stub files seems wrong

I'm currently trying pyTango 10.0.2 and the generated stub files just seems wrong to me, like most methods are marked @staticmethod and accepting, or not, an obj which seems to be the usual self. This just don't work with autocompletion from VSCode.

For example, the following method from DeviceProxy class:

@staticmethod
    def state(obj, *args, **kwargs):
        """
        state(self, green_mode=None, wait=True, timeout=None) -> DevState

The signature is not even matching the docstring.

Is this a recent bug or has this never been reported?
