An admin/teacher of a university that wants to teach Git to students
in a class? Better be safe than sorry and explicitly ask for advice because...
we cannot trust the default?

And now I am arguing that "by default" we should not give advice 100%
of the time, but only when we think it is appropriate. You may disagree
(as a teacher see above), so you can slightly change the setting to give
out advice more often again?

I think this is what I did in some of the submodule code as well, which
is why I assumed it's ok (or rather the projects groupthink on how to do
"default on but still different than explicit on")

If you think this is wrong, what is the idiomatic way to solve this problem?

Thanks,
Stefan
