How to make Pylance assume try/import always resolves without disabling whole Unbound checks?

[Kein]

main.py

from typing import TYPE_CHECKING, Any, Dict, Optional
if TYPE_CHECKING:
    import macros  # post-process

#  main logic/code

macros.py

from typing import Any, Dict, Optional
from datetime import datetime

#  additoinal logic/code

cat macros.py main.py > main_compiled.py
(macros gets pasted at the end of main)

Normally I'd just use import.tools or some monstrosity in macros.py like:

try:
    from typing import Dict
except ImportError:
    #  noop because imported in main.py already
# oh but it gets better you need to import EVERY type separately because it may fail on the first and wont import the next
try:
    from typing import List
except ImportError:
    #  noop
# madness continue

but the issue is that I lose all kinds of type hinting and semantics and autocomplete in macros.py because Pylance assumes try/imports are not resolved/unbound (and import.tools are runtime).
