[Auto Import] Better auto-import priority (Lower the priority of superseded modules)

[BlueGlassBlock]

According to this doc site, lots of modules are superseded / deprecated.

However, lots of them still have high priority and break users' auto-import experience.

For example:
type from typing imp and the first entry is imp module.
Option's auto-import entry is from optparse rather than my local module.

And some related annoying imports:
from ctypes import Union rather than from typing import Union (also typing.cast)
from re import I (when completing from ... import ... too quickly)

I believe the auto-import problem has been lingering for quite a long time.

Is it possible to address a better algorithm (context-aware / prediction based on user data) to improve the state?

If not, could you please add a way for us to filter out those modules we don't want? (For example this, from #2535)

That's why I choose PyCharm...
Just kidding, sincerely hope that your great job could enhance it.

Moving this issue to discussion as an enhancement request for comments and upvotes.

I experience something similar, that I think is also related to auto suggestion logic. Normally when typing cast the ctypes suggestion is usually before the typing suggestion. This is common with different packages as well.

Other thing that I found, was that suggestions won't prioritize local packages, I have a package called BaseService that is used a lot across the application (a lot of modules import it), and every time I start typing BaseService always (100% of the times) recommends BaseServer from socketserver which is a package that I've never used before and doesn't appear in my project anywhere.

Maybe it could make sense to have a higher ranking for local objects (local in the sense of the user's project instead of third party libs)? Other option is maybe to keep track of import frequency (objects that were imported a lot have a lower threshold to appear in suggestions)? Besides the deprecated being lower ranked, maybe most commonly used imports (from Github's Python's codebases perhaps) could also be higher ranked? Examples: packaging appears before pandas and numbers appears before numpy, should it (honest question)? I don't know which is more popular.

At last, I also found that quick actions suggestions (Cmd + .) don't really work very well when doing something like from pandas import .... it won't show the available objects. A lot of libs have __all__ which maybe can help?

Anyways, just ideas.

Another auto-import problem that I always face is when I need to import something like Self it suggests the import from typing even tough I'm using python 3.9 where this is not yet available, I never got it to suggest the import from typing_extensions

[DanielRosenwasser]

I actually filed an issue about suggesting newer features from typing over typing_extensions: #4993

we have open PR to address this. @bschnurr do you have ETA for your PR?
