I am not sure that this is correct. It would treat strict differently.

I'm not too familiar with this callback so I had just replicated #9203
We can instead replicate main.py and do

    def set_strict_flags() -> None:
        for dest, value in strict_flag_assignments:
            setattr(options, dest, value)

would that work?

Yeah, something like this would work (I hope so, at least)!

I'm afraid I'm not familiar enough to know how to continue. The blurb I linked refers to a strict_flag_assignments variable that gets populated through some deeper method. Do you think strict flags are something that would be useful when parsing config files in stubgen.py? (I'm not sure of what strict flags even are, maybe with some extra context I can help implement something more robust)

Otherwise, would you be ok leaving the current implementation as is (it at least matches the existing [already merged] stubtest.py PR that inspired my PR) and someone more knowledgeable could propose a better handling of strict flags in the future?

Thanks for your quick response!

Ok, if this is hard to do, we can skip it for now :)
