Autoimport itemkind

[bagel897]

I'm working on an autoimport completion provider similar to pyright's. This is their implementation:

Mine will index all available python files and determine the availible names and type of each kind to provide pylsp. (Working on the itemkind part right now. )
Say we have this file as an __init__.py (this is all parsed in ast by file) (this example is truncated from arrow)

from .factory import ArrowFactory
__all__ = ["ArrowFactory"]

Earlier I just said, __all__ has ArrowFactory, that's the avalible names in this module. But now I want to know the ItemKind of ArrowFactory. Since each file is parsed seperately, determining the type of ArrowFactory is impossible without importing the module afaik.
Should I give ArrowFactory a default itemkind, and what itemkind? And do you think it is fine if I just use __all__ in __init__.py files?

(Pyright seems to have solved by only indexing the standard library (which can just be imported without using ast, and are largely single- file modules anyway), so we can't use it as a reference.)
