Review comment (suggestion):
It seems like it makes more sense for `name` to be a string. Also, `source`'s keys are strings (and the values can be many types, because they represent arguments for `moderngl.Context.program()`): 
```suggestion
        name: str | None = None,
        source: dict[str, Any] | None = None,
```

        filtered_shader_attributes = filter_attributes(
            self.attributes, shader_attribute_names
        )

            filtered_shader_attributes.tobytes()

        if self.indices is None:
            index_buffer_object = None
        else:
