[FeatureRequest] `F2` rename import typing, should result changes in function annotations

[loynoir]

Actual

Change type from pre to post

Pre:

if typing.TYPE_CHECKING:
    from custom_types import pre

def parse_args() -> 'pre':
    return foobar

Post:

Error: Name "pre" is not defined

if typing.TYPE_CHECKING:
    from custom_types import post

def parse_args() -> 'pre':
    return foobar

Expected

Change type from pre to post

Pre:

if typing.TYPE_CHECKING:
    from custom_types import pre

def parse_args() -> 'pre':
    return foobar

Post:

if typing.TYPE_CHECKING:
    from custom_types import post

def parse_args() -> 'post':
    return foobar

I'm quite confident that this is not going to get fixed, because it just does not have a high priority. But I'm very happy to accept pull requests. In the meantime I can recommend using from __future__ import annotations and not using string literals as annotations.
